Yes, but you tend to use commands out of their proper context.

\fromplgivenetx is a <transformed font> command, and as such only supposed
to be used in the second argument of a \transformfont command. It should
work for you here, but there is no guarantee that it would work with future
fontinst versions.

Similarly \installfont is an <install command>, and may only occur inside a
\installfonts ... \endinstallfonts block. This is what causes the error you
get.

A cleaner way to do the above would be:

\input fontinst.sty

\transformfont{test-Cn}{
  \xscalefont{850}{\fromplgivenetx{test--base}{mn-integral}}
}

\installfonts
  \installfont{test}{%
     test--base encoding mn-oml,%
     unsetj,%
     test--lcdfj encoding mn-dotlessj,%
     unsetint,%
     test-Cn scaled 1100,%
     mn-omlint%
  }{mn-oml}% Any reason why this is not the standard oml?
  {OML}{test}{m}{n}{}
    % You might want to check whether the 'n' shape is the default
    % shape for OML fonts. I've got a hunch it isn't.
\endinstallfonts
\bye
