Yeah you can, go to your system preferences and then to sharing, it should say computer name at the top, just type in whatever you'd like. Hope that helps!
Try going to Finder> "Macintosh Hard Drive"> Users> "Your User" and double click the name you want to change, it should let you rename it like with any other thing that you would double click to edit.

tell me about it. I did this on the first day I got my new iBook after I transfered everything from my mini. Youch...I wound up just reinstalling the OS so I didn't have to deal with it. What a mess. You would think that Apple would stop you from making such damaging changes so easily.
