Sure. That's what I've been doing.

However, Dulls (and probably most laptops) don't run for more than an hour
running CPU intensive applications (such as any kind of audio DSP) on a
fully charged battery. The batteries aren't cheap, either.

I have enough to think about on stage without playing count down with my 
pc.
You are also going to have quite some fun re-charging a battery while you
play (I'm not sure of how you would do this, without using a second laptop 
-
I've looked for chargers), so for a one hour gig, you will need at least
three, if you intend to bring a backup.

My work's IT department says that the batteries don't last for more than a
year, either - they are constantly replacing them, as a matter of course.
(Perhaps yours will last longer - my laptop is on 10 hours+ each day) Make
sure they are covered by your warranty.

This all brings up another of the dull short comings - switching the
batteries while on wall power can crash them. Again, customer support says
there is no fix.
