I've never done this so I can't say for certain. However, I would 
approach the upgrade with confidence because:

(a) mdadm identifies RAID volumes by scanning the partitions, not by 
looking for specific devices, so it should still work even if the device 
names have changed between FC2 and FC4.

(b) if it isn't going to work, you'll find out at an early stage of 
running anaconda because it won't be able to find the filesystems for 
your existing system when it's looking for a system to upgrade. So you 
could just reboot at that point and be back in FC2 where you started from.
