Probably. Give it a try. It will have to be an OS X version that would be capable of booting the smaller MBP.

It may be possible if both computer are of the same vintage, IE made around the same time and had very similar hardware.
About the only thing different between the same vintage Mac 13" & 17" is the 13" has on chip graphic were as the 15 " can and more then like does have a dedicated graphics card. But as the OS is the same for both it should contain drivers for each type of graphics chip.
Give it a shot and post back with results.
