Yes; there is no restriction in the spec that constrains gzipped content
to only be served over HTTP.

You are correct that a typical file system cannot convey an equivalent
to the encoding parameter (though it can detect this based on magic
numbers, see the gzip RFC) but then again, a typical file system cannot
convey a full media type either (and again, it can detect this based on
various things like Mac filetypes, filename extensions, and so on). This
is the same for other protocols such as ftp.
