You can put an OS 9 system folder on the system, but the computer will not boot off of it. The best you can do is designate that folder for Classic mode in Tiger(and earlier).
Read over at OS9 Lives, and you might find some magic that will allow you to boot into OS 9, but I don't know offhand what it involves.
All of that aside, your computer has a Radeon 9600 GPU. OS 9 and Core Image GPUs tend to be mutually exclusive, and the drivers just aren't there to run the GPU correctly. If you can get it to boot to OS 9(again, with some tricks that some very smart folks have spent a lot of time figuring out, so I don't want to deride their efforts), you'll likely find the graphics performance pretty low and also very limited. There's a chance you'll end up with an 800x600 window in the center of your screen, as I had on a TiBook before I found the correct OS 9 install for it. You may also find that you're limited to 256 colors.
If you want a laptop to boot into OS 9, the best choice-bar none-is a 1ghz Titanium Powerbook. It fully and natively supports OS 9, although you'll need the system-specific install disks for full functionality under OS 9.
