I think it does. That code is pretty much a Konami-Nintendo relationship. The only difference I noticed between Salamander and Life Force was as I mentioned before...the HUD. On Salamander it's a little more detailed with P1 Score on top of P2 Score where as on Life Force P1 Score is on the left and P2 Score is on the right. But I believe I used the code a time or two playing it through emulation.
I'm editing this for a correction. I did some research on this and ... sadly ... no, Salamander does not have the famous Konami code. Apparently it does, however, have a different ending.
