No you can not, it would be a clear violation of the NEC which in all common circumstances requires at least #12 on a 20 amp circuit.

I do not believe that it would be dangerous since the load is well within the capacity of #14, and in some countries it would be allowed. But under the NEC, no way.
Either use at least #12 or use #14 on a 15 amp circuit.
