Yes it is possible, but you must first completely erase the OS X 10.5 boot volume. Therefore it would be prudent to copy or "clone" it before doing so.
Use your original System Install DVD that shipped with your MacBook Pro. Use Disk Utility to erase the volume, then install its original operating system. Install the original bundled apps as well. Following that, update everything as necessary using Software Update.
After that, you may be able to install the programs you have been accustomed to using with Leopard, provided they are compatible with Tiger.
This is the PowerBook forum.

Thanks John, as there doesn't seem to be a way to migrate backwards other than to erase and reinstall I will for the time being leave things as they are and reinstall 10.4 when I no longer need the legacy apps. Regards, K

That is correct, but installing Tiger on a separate (empty) boot partition is also an option. This can be a partition on your existing hard disk or an externally connected volume.

That's sounds like an excellent idea.

To expand on John's good advice, when he writes:

remember that few PowerPC Macs can boot from a USB device. If you want to do this from an external, the external needs to have FireWire connectivity for reliable booting. And FW is faster anyway

I think partitioning the existing internal drive is the answer, reinstall Tiger and the two apps I urgently require. This way I won't have to mess around with a zillion setting but will have a speedy OS with the legacy apps that I need.
I'm grateful for your thoughts. This is a great forum.

Dear John and Allen,
I'm thinking Disk Utility in 10.5 will allow me to create a partition on my existing internal hard drive on PB G4 which I can then install Tiger via my original installation disks?
