Yes. Gasses are compressible fluids, and gasses can be in a nearly-incompressible flow.
The keyword here is "nearly". As in, it will not exactly fit experimental results, but it is good enough for most purposes. If the pressure drop is INSIGNIFICANT compared to the static pressures themselves, you can get away with treating it as incompressible. It is also essential that the speeds involved are much less than the speed of sound in the gas.
If you model the flow as compressible, you will introduce a lot more mathematics than you intended to consider. And it wouldn't really be worth it, because in many cases, you can get away with an incompressible flow model.
