You could always try but I would not hold my breath.

Restore discs, which are usually grey, are generally machine specific and will not install on machines other than the one it was designed for.

You have at least two things going against you here:

1. G4 has a PPC processor
2. The iMac has an Intel processor.

Given that, I would not be surprised if the Restore disc took one look at the G4 and tell you it cannot install on this machine.

10.5 is the last version of OSX that will install on any G4 or G5. I wouldn't do that unless you have at least a 1 GHz processor, and a GB of ram. Your probably better off just sticking to Tiger.
