Doubt it - the tram tunnel is huge** so it would be a lot wider than
that. And its not very deep anyway, much shallower than the central
line.

Makes me wonder whether the door at that end of the platform leads
into it, or could it just be a disused interchange with the picadilly
line platforms?

Probably something like that.

** Went down there about 7 years ago when they had an art exhibition
in the tunnels. Usual talentless modern art cr@p - the people in
charge were most put out that almost everyone was down their to
explore the tunnels , not stare at repainted hamster cages stacked on
top of each other or whatever mindless rubbish the "artists" had
thrown together.
