Hard to say, but in my opinion, the answer is YES. I don't think you'll have any chance of finding the broken trace, I sure can't see it in that photo and I'm guessing it's not visible. However, I bet one of those tiny components near where it used to be was directly connected to it. You would need either a wiring diagram or trace an undamaged motherboard with the ohms setting of a multimeter to see if any of those components were directly connected to the terminal. You could then probably reform that gold terminal with tweezers, and solder a very, very tiny wire between the solder end of the appropriate component and that terminal and use a good strong epoxy to glue the terminal back down to the board in its correct location. You'd need a really good pencil-tip soldering iron, really steady hands, and good soldering skills to do that kind of micro-soldering.

I'm thinking to part out the RAZR M that I bricked over the weekend. If you're interested, I can test my board to see if any of those nearby components have continuity to the terminal.

Not sure if you're still wanting to fix it, but I pulled my bricked RAZR M apart today and saw this is a pretty easy fix.
That terminal connects directly to the lower of the 2 black SMD components. In fact, I didn't notice before, but in your pic there is still some visible trace connected to it. Should be pretty simple to epoxy the terminal back onto the board and solder a short piece of wire onto the remainder of the trace.
