Yes it is possible.

problems i see

fidelity of the anti noise generated could be tricky

fidelity of the sampling might be hard but not sure

depends on the response of the mic i guess

Automotive ANC isn't anything like noise-cancelling headsets. That
technology is only possible over a very small area (the point between
your ears). I'd expect any noise-cancelling used in power tools would
be more like that used in automotive, where a lot is known about the
noise beforehand.
