You should be able to, but make sure you have the latest loader
in the EFI system partition. The 8.1 loader will not be able to
boot a -current kernel.

As a precaution, you could create a new partition for the FreeBSD
-current installation so that you preserve the FreeBSD 8.1 one.
You can even leave the FreeBSD 8.1 loader on the system partition,
though the latest loader should boot an old FreeBSD kernel just
fine.

FYI,
