I think there would be no harm in lightly oiling the bobbin race. What I am wondering is if the "oil-emitting bearings" in the bobbin area have dried up, thus requiring a maintenance visit. Seems to me manual oiling of that area would not be harmful. Unless the bobbin area is largely plastic, as oil might interact in some negative way with the plastic. If everything is metal, I would try running an oiled finger around the race.
