At
boot.fedoraproject.org none of the available downloads are UEFI compatible. There is a
UEFI pxe boot test case so it looks like it ought to work, but I thought I'd point out
that at the moment it's unclear how to do this on UEFI.

(This test case might be outdated as it references bootia32, but we aren't supporting
32-bit EFI right now.)
