Sure as long as the new partition starts on the same block and is longer.
It was a bit more difficult with UFS but for zfs it is very simple.
I had a few systems with two ufs root slices using live upgrade:
<slice 1><slice 2><swap>
First I booted from <slice 2>
ludelete "slice1"
zpool create rpool "slice1"
lucreate -p rpool
luactivate slice1
init 6
from the zfs root:
ludelete slice2
format:
remove slice2;
grow slice1 to incorporate slice2
label
At that time I needed to reboot to get the new device size reflected in
zpool list; today that is no longer needed
