Provided that the apparent roof slope in the picture, allows a smokestack of a loco to reach the back of the shed, you can always add another smoke jack.
Judging from the position of the smoke jack I'd say yes. If the engine could not run under its own power then it could be pushed in in either direction by a yard switcher. After it was able to be fired up then most likely the switcher would drag it back outside to begin the start up without asphyxiating the workers and crew. The small windows along the sides would more or less confirm the relativley poor ventilation.
