My brother says, yes, you could skate faster in a vacuum because that would remove the air resistance.
He also offered that in low-gravity, the air would be less dense (if you weren't in a pressurized environment), so you might have a little less air resistance. However, this would be balanced by a reduction in the force you could exert to push yourself forward, because the friction between the wheels and the ground would be less.
