Can I Reinstall/Format Leopard without Hurting XP?

Hi my Leopard is running very slow and weird iTunes is all jittery and programs seem to like to spaz sometimes, so ive decided i'll reinstall leopard the thing is tho i have windows xp and dot wanna delete the partition and reinstall windows Xp its one of the most annoying things i do in life, lol anyways so can i install leopard then run the boot camp assistant and just find the boot camp partition click ok and be happy?

BTW. Im running the Aluminum Macbook 2.0GHz so its not a ram issue.
