Difficult to answer without audio, but i would say no unless those frequencies that the ears won't perceive but that the body will, are creating too much indesirable tension (phisicall).

Dear all,

I'm in the process of bouncing down stems. Since I'm working at 96k and
mostly with spectral processes that may potentially produce high-energy
components above 20k I was wondering if I'd gain a little bit more headroom
by putting a mastering equaliser on my master track and gradually rolling
off everything above 22k or so? I've never done this but this piece is
really high-frequency orientated and I think this would make a big
difference.

Many Thanks
Peiman

Removing inaudible frequencies will absolutely increase headroom.

If you have float samples you could just increase your headroom --
there is more than enough to handle this. Then apply EQ at the end.
I'd compare this with doing the EQ first using (a) ABX tests and (b)
high-resolution, high-bandwidth spectrograph.
