Suppose you are in the final quarter of a loop maneuver, looking at the
ground. Your speed is high and you are pulling back hard to bring the
plane back to level. Can that result in a stall?

Yes indeed. Low altitude vertical recoveries and the safety issues
associated with them as they relate to the air show demonstration
environment happen to be a specialty of mine. There is an feature article
dealing with what I have to say on exactly this issue in the Feb 2004 issue
of Aeroplane Monthly; "Precision Decision" by Gen Des Barker of the South
African Air Force. You can either obtain a back issue from the publisher or
if you email me back channel, I'll be happy to send a copy of the article to
you on a pdf file. The article deals almost directly with your question as
that relates to flying the P51 Mustang, although it covers a great deal
more.
