Not quite, however you could do:
# zfs create -o canmount=off rpool/vm
# zfs create -o canmount=off rpool/vm/linux
# zfs create -o mountpoint=/export/vm/linux/ubuntu00 rpool/vm/linux/ubuntu00
In general though, don't worry about extra filesystems being mounted
(unless you're dealing with thousands of them) I've 44 on my desktop,
and have no problems with it, and I leave all of them mounted.
Thinking of a filesystem more as an administrative point of control can
be helpful. (eg. set properties to be inherited by all children, a place
to do 'zfs snapshot -r filesystem at snapshot', etc.)
