the disk may be tailored specifically for a laptop. Although there is no difference in the OS on a laptop and the OS on a desktop, the installer may be configured to only work when it recognizes a laptop Gestalt number.
The other thought is that what you are attempting is not quite legal. Although there are no serial numbers to enter for OS X, you would still be violating the End User License Agreement that is part of the OS.

Just bought a powermac g4 from a guy on craigslist that came with OS X 10.2.3 installed.
I would like to install OS X 10.4.9, but don't want to buy it. Can I use the installation DVD that came with the macbook I bought in april. Is this possible or will I have to buy a new copy of OS X?
