Hmm, that one seems to be 16mm wide, which still looks a bit too wide to fit. Maybe it's a different one?
ESP04 looks possible, but it has no antenna.
To be honest you could just use one of the through-hole ESP01 boards and solder it into the 0.1" holes by the side of the proto area. All you have to do is connect 4 wires (but again, you'd almost certainly need to add a 3.3v regulator)
