Yes, if it meets the minimum requirements:
Lion System Requirements
Macs that will support OS X 10.8 Mountain Lion
As usual, the newer the Mac the better:
Macs that are NOT expected to support OS X Mountain Lion
Older Macs and those with weaker GPU’s will likely be left behind:
Your model must have a 64-bit EFI boot ROM. See OS X v10.6- Macs that use the 64-bit kernel
An easy way to tell if you are running a K64 kernel is to use the uname command-line program. The "x86_64" in the excerpt below means that we are running a 64-bit kernel. If the output showed "i386" instead, that would mean a 32-bit kernel.
$ uname -a Darwin... root:xnu-1456.1.25~1/RELEASE_X86_64 x86_64
If your computer does not boot into the 64-bit kernel automatically you can force it to by restarting and holding down the "6" and "4" keys after the chime. Re-run the above command in Terminal. If you don't see "x86_64" then your model does not have a 64-bit EFI boot ROM and cannot boot Mountain Lion.
