Is it possible to have an instance of GM Force (even just a singular one) without the session/campaign being an all-out Railroad?
...
If the answer is indeed “yes”, then isn’t it useful to have distinguishing terms?
No actually, it does not appear to be useful.
You don't need to define terms for everything that is different; it's only useful if it makes comprehension easier. Since the only difference between railroading (a well know term) and "GM Force" is duration, it doesn't seem worth teaching the world that "GM force" is not a superhero group, when "railroading instance" works just as well.
Even for this thread, it's not helpful. The quote given by the OP is all about something that is happening all the time -- it's ongoing advice on how to do things in Traveller. It's specifically NOT "a singular" incident. So we're discussing "ongoing sets of instances of railroading" as the topic for the thread. For which by far the simpler term is, simply, "railroading".
I don't have any real objection to the term; if you want to use it in this thread, no worries there. My main concern was to make sure that you weren't thinking it any different form railroading, except in duration. I don't think it's worth giving a name for, but if this time next year people talk about "GM force" and not "railroading", then quote this post and make me look foolish!
