If you have #14 gauge wire then you might still be able to use the

NO NO NO NO NO !!!! This is UNSAFE, because it enables plugging in a load

will draw more current than the wire can safely carry. DO NOT put a 20amp
plug
on a circuit that has only 14ga wire. UNSAFE. ILLEGAL.

It is probably unsafe, but not necessarily.
They could have put a 20a plug on a device that draws 3a.

No, it IS unsafe, period -- because it enables plugging in a 20A load on a
circuit that cannot safely carry 20A. Maybe the load the OP is going to plug
into it today only draws 3A -- but you can't predict what might be plugged in
there tomorrow, or next week, or next year. It absolutely is unsafe to attach
a 20A receptacle to a 15A circuit. There is a REASON why 20A plugs and
receptacles exist: to keep them from being plugged in on 15A circuits.

State your source.

It is 100% legal to use a 20A receptacle on a 15A breaker. If you
plug in a appliance that draws more than 15A then the circuit is
protected by the 15A breaker. (That is what it is there for)

It won't work if you try it, but that doesn't make it unsafe.
