Yes - just copy the entire ArchiCAD 10 folder in the Applications folder of your G4 to your new Macbook. You might, actually, want to burn it onto a CD for future re-installation, since eventually your G4 may not be around.
Download the current WIBU keyplug driver from the Graphisoft web site and install it on your Macbook.
Older versions of AC will run fine on Intel Macs in emulation mode (Rosetta), but the installers themselves for the old versions only run on PPC Macs (e.g., G4, G5).
Graphisoft has also uploaded copies of AC 7 USA and AC 9 USA that can be downloaded onto all platforms (including Intel Mac) for the purpose of opening and converting older projects.
