Yes, you can!
If you have a Core Duo Intel Mac, you want the i686 version of Fedora.
If you have a Core 2 Duo or later Intel Mac, you want the x86_64 version of
Fedora. (See the question about getting Fedora.)
Note that some things may not yet work perfectly on Intel Macs.
mactel-linux.org is a good site
for information about running Fedora (or any Linux) on a Mactel machine.
If you have a G3, G4, or G5 Mac,
there
is no longer an installation disc available for your machine for Fedora
13/14/15.
