Not unless you have an earlier MacBook Pro like the 1.83 Ghz through 2.4 ghz model listed here at

This one listed here was the last model that could run Mac OS 10.4. Apple doesn't allow earlier versions of Mac OS 10 to be installed before the original OS that came with the computer.

Is it easy to remove leopard and how do i do this,Colm
Expert:  Rob replied 8 years ago.
All you need is the install disks for Mac OS 10.4. Insert the disk, restart the computer while holding the C key. The computer starts up by the install CD. You will be guided by the CD through the installation. If you need to save your personal information on your computer without deleting it, you need to select Archive and Install option explained by Apple here:

Make sure you have one of these earlier MacBook Pro models that will allow installation of Mac OS 10.4. If you just bought it brand new from the Apple Store or from an Apple Retail Store it is most likely a newer model and will not allow installation of Mac OS 10.4.
