Almost the same SQ footage, I would say yes. I have a 2 dog that heats our 10 x 12 and 12 x 14 just fine. Been in the teens, just smaller box so takes work to keep it going all night. 
I have two Three Dogs and a Four Dog in our cook shack which is 10 x20 and not as tight as a wall tent. The four dog heats it fine.
Wish I could find another Dog Stove for sale.
I used a Camp Chef Alpine wood stove this year and it got down to -5 at night. The stove had to be stoked every hour with the dampers wide open to keep it almost bearable (the tent was still frozen inside). I am looking for something that will heat the tent when it gets bitter cold. Do you think it will work in those conditions?
WOW, still frozen on the inside? What kind of tent are you sleeping in? In the past I've used a standard Cabela's wood stove in both a wall tent and my kitchen tent (shelter Logic portable garage type. We've been into single digits but never had an issue keeping the tent warm. Does your tent have a fly over it? I know on either of mine, that fly was good for at least 20% heat savings. Over the years we've also adjusted a number of things to make it more efficient. The best is making sure we have an ample supply of madrona wood for the camp stove, burns long and hot, keeping coals until the morning.
