sure, why not.
microstrip has a limited range of un-loaded Q's for various types of resonators, so if you try to make the bandpass filter too narrow, you will end up with very high insertion loss.
that is why in demanding applications you can still find things like waveguide or dielectric resonator filters. Below 5 ghz, you almost exclusively see high K ceramic resonators making up the N pole bandpassfilters, or other things like SAW or BAW filters for very narrow band.
