Absolutely, yes.  I do this all the time.

For example - I added an SSD to my laptop, added it to the Volume Group,
and moved the "VM" volume group to the SSD.  As far as anything else was
concerned nothing changed.  Now if I'm on the deck, the bus, or the
train[1] I can boot, snapshot, whatever my VMs on the SSD - it is fast
and the battery last for &@^*&$ ever (since playing with VMs devours
I/O).  

[1] The train provides power, but sometimes you don't feel like asking
your neighbor if you can string a power cord over their lap (especially
if they are sound asleep).
