Yes and no. In sprite world, there are no walls or anything that will cause a disconnect if you pass through it. The space/void can be walked in just fine. But in a lot of other dungeons there will be walls or other things that if you walk through them it will disconnect you. You cant move as far as you want when teleporting, so you would have to make multiple jumps to get to the boss room. Each jump would risk landing somewhere that could cause a disconnect. So the success rate of doing something like this would be pretty small imo.
