The topcase will work, to a certain extent - the trackpads are not interchangeable. Keyboard ribbons are the same, trackpad ribbons are not interchangeable.

You can connect the topcase but where you’ll run into problems is the USB port - the screw holes are in different places. I tried this myself, to see if it worked, with a 2015 trackpad, and the only thing which wouldn’t work was the USB port as it was too loose with only the one screw attaching it.

EDIT: Just realised that you were talking about a 2016 board and 2015 topcase. I haven’t tried it this way around, but I’d imagine that the USB port will still be the issue, as there’s less space on the 2015 topcase.
