I would boot into the Fedora distro, and rename the groups.
I am actually supprised that Fedora didn't see your SL5 LVM groups and volumes 
and suggest different default names.  But, it's going to be really hard to boot 
into SL if it keeps seeing the Fedora stuff.
I am quite sure that you can rename the LVM volumes and/or groups after the 
fact.  But, you then have to make sure that grub and fstab are adjusted 
accordingly.

Oh, and I believe it is
   system-config-lvm
unless they renamed it in Fedora 9, but I don't see why they would.
