You can indeed.

But look carefully at the full data sheets on any you intend using. The capacitance value is strongly affected by the applied voltage. Often not mentioned in data, these things are also highly microphonic.

These parts are useful as decouplers on power supplies and offer high density with freedom from the drying out lifetime limitations of electrolytics, but they re highly non-linear and are effective vibration transducers.
