So their reason seems to involve some usage of the NES Ness pun, but does that pun work in Japanese? Is there an equivalent shortening of Famicom, and does Ness's Japanese name bare any relation?

Pure curiosity, the author can do what they want.

According to the Earthbound wiki, the default name of the protagonist in Mother 2 (the Japanese version of Earthbound) is ネス (Ness), which doesn't really resemble the name of the Japanese name of the console (Super Famicom).

The default name of the protagonist of Mother 1 (released on the original Nintendo Famicom) was... ニンテン (Ninten).

Considering that Earthbound parodied Western cultural stuff, the names probably wouldn't need to be Japan-specific.
