Yes, but just deal with it in a straight up manner.
-blam!-ing with the thermostat is the easiest way to enrage someone who likes cold temperatures. You could probably buy a fan heater for $20 and that would warm your room up nicely.
If you don't want to ask them about it upfront, just find the simplest solution. Breaking the thermostat will just come back to bite you in the arse later on.
