Only by editing the freebsd-update script or by modifying uname(1).

In general it's a bad idea, since FreeBSD Update looks at what files you had
installed from the old release and whether you've modified any of them in
order to decide how to upgrade to the new release.  If you confuse
freebsd-update enough to convince it to upgrade your non-supported installation,
it's likely to overwrite modified configuration files or not update files.

There isn't any good solution here, yet.  I might add support for the snapshot
ISOs at some point (at least for upgrading to/from them -- there will not be
security updates built for them).
