Wow I have never thought of that, maybe the top cup is threadless and since the fork was threaded they just mounted 2 locknuts on top of the threadless top race? I only see one lock nut in the picture, maybe the other is hiding. Anyhow, yeah tap that bolt down and twist that stem free! Unless someone tightened it so hard that it expanded your steertube, it should break free.
