can a thinkpad run OSX?

It is possible... but not out of the box, you've got to do some firmware changes and stuff I believe. I wouldn't recommened it though, speed and performance will be severely hit.

It's possible but not legally and unless you have exactly the right hardware you will probbably run into a lot of problems getting it to work. You can also forget about support and updates too. My advice to you is, if you want a laptop that can run OSX then buy a real Mac. Anyways, for your entertainment, here is proof that it can be done on a non Apple laptop:
