It's "possible" but I wouldn't recommend it until 12.04.

In my experience upgrading will at least require you to umount
/lib/init/fstab and tty[1234] and console in /dev, otherwise udev,
mountall and a few others will fail to upgrade.

We fixed all this in 12.04 so that a 12.04 to 12.10 upgrade will work
just fine, sadly these required substantial changes to upstart,
mountall, udev and lxc itself that are too risky to backport to older
releases.
