I remember hearing that one shouldn't grill over a fire with a
refrigerator shelp as the grill (even when they were just metal, and
not covered with vinyl), but

Is it ok to grill over a fire using the shelf (grill) from a kitchen
oven?

Sure. The refrigerator shelves can be galvanized and the zinc will
contaminate the food. You should not ingest large amounts of zinc. Grates
from the oven do not have that type of coating and are perfectly safe to
use.
