This all comes down to what is being used as the bootloader for your dual boot setup. If you have separate hard drives for Win7 and Linux, and you're using your BIOS to select which drive to boot from, then what you're asking should work fine. If they're on the same hard drive, proceed with a little caution. I would have backups of your /home partition and Win7 just in case.
