Yes, you can have any number of operating systems to boot. I routinely
have a system at work with RHEL 3 and RHEL 4 as dual boots. 

One issue that could cause some problems is your home directory. I've
run into this issue when dual booting 2 different versions of the same
os where the GUI saves its configuration in your home directory. 

On the system at work that I dual boot, we share our home directory
between the 2 RHELs. 

Just make sure that the /boot and /boot/grub data is set up properly.
At work, this is handled through Intel's EFI, but at home, I never
create a separate /boot. While (or after) installing and OS, I then
either edit the /boot/grub/grub.conf (menu.lst) to point to the other
OS, or I use SuSE's YaST.
