I'm not sure about Punkbuster, but legally, since you own the game, you can do almost anything in this thread.
Capt Caveman directed you to a program called Alcohol 52%, which you can find via google. Use that program to create an image of your game disk on your hard drive. You then use Alcohol 52 to 'mount' the image, meaning Windows things the image is a drive with a disk in it. Often you can run from that virtual drive. Another program, Daemon Tools, is my preferred utility, but both work well. Sometimes you'll still need to use a CD crack though.
Again, I'm not sure if any of this will get around punkbuster. I'm not very familiar with that program beyond the fact that it banned me for using a widescreen hack in BF2.
