Personally, I have never put a name to address a particular person on a CV or cover letter. I've never even written "To whom it may concern." If it concerns the person, then it does, and they will read it. If it doesn't, they'll pass over it. (Edit: What I frequently use on cover letters is "Dear sir(s), ma'am(s):")
That said, writing the wrong name, like you said, will simply cause confusion. For instance, the person whose desk it does land on may wonder what it is for, and the person whose desk it was supposed to land on will wonder where it is, or worse yet, never know that he was supposed to receive it.
Personally, I wouldn't write any name on it. A generalization won't hurt, and a specification could potentially. As for making it show that you have put some effort into it: I'd save that for the interview or a less official document. The CV is basically just for the employer to learn who you are and what skills you have. Unless you're applying for a job in company research or something, including the name of the recruiting manager won't really help you get the job.
