It is a possibility that your interviewer will talk to your current manager. Because interviewers don't always just stick to the list you give them (and they're not always wrong to do so). For example if none of the references you provide were managers, you only reference peers, this is a red flag for them. Or if they notice someone in their network they trust has worked with you, they'll ask them about you.
From what I understand, you've been made redundant a month ago, so your "current" manager is really your ex-manager. It's not like you're still working there and/or wouldn't want your manager to know you're job hunting. Talking to your current manager is a big no no for interviewers. But if he's your ex-manager, and if your interviewer knows him, and if he knows that he's your ex-manager, there's a chance he might talk to him about you. There are a lot of ifs there, so I think the chance this happening is rather small.
So I wouldn't mention it at your interview. If he were your current manager, and you really wanted to make sure they don't talk, you could have said something along the lines of "I know you're working in the same terminal as my manager [manager name]. I haven't told him I'm job hunting, but I have other managers as references I can provide when you need them." But since here you'd be telling him to not talk to your ex-manager because he doesn't like you, or because there are issues between you two, this won't reassure your interviewer. And again, there's only a small possibility he talks to your ex-manager, so I wouldn't risk bringing him and your negative relationship up on the off chance they do talk.
If he does talk to your ex-manager, it won't be the end. You have your other references, the awards and bonuses you got from your good work. Just be ready to answer questions about your ex-manager if it does come up at some point in the interview. Have a short, neutral statement prepared (don't overtly criticize your ex-manager). You want to sound confident and calm, not panicked. One bad reference shouldn't dismantle your good work and good references.
EDIT : If you absolutely want to warn this interviewer, don't be vague or general. You don't want to give the impression you have a negative relationship with many managers from previous jobs, and that you willy nilly advertise this fact. Also, don't write it, say it when they're asking for your references. Tone here will be important : be calm and confident, not nervous and panicky. You just want to convey some information that might be relevant to the interviewer, not a live bomb. Keep it short, something like this (adapt accordingly to the specifics of your situation) :
I would like to inform you that I didn't end on good terms with my last manager, and because of that he might have a biased opinion of me. I have other managers, including from my previous job, as references. Usually I wouldn't mention this, but since you work in the same terminal as him I wanted to make sure that if you talk to him, you know there might still be some bitterness lingering that might color his feedback.
Again, I wouldn't do that. The chances are quite small that he will speak to your ex manager, and if he does your strong work achievements and other positive references will more than balance things out. Mention this, and your chances that he talks to him will actually probably go up.
