I'm not sure whether there was an update in the installation discs between and , when I bought my computer. Even if I knew a way to use another version's install media So, yes, it is possible that your MacBook requires updates included in a later version of Leopard than your friends MacBook required.

Then just use his install media in his MacBook to install Leopard to your drive. Then update the install to the latest or at least a later version of Leopard. Then move it back to your MacBook.
