An outward bulge in a can would be the result of gas pressure
build-up.  We should all be able to agree that the most common
process where honey would generate gasses would be fermentation.

How?  Neil Young made an album about it - "Rust Never Sleeps".
Can lids and bottoms are attached with nothing more than "crimping",
and older cans were steel, so over time, the seal integrity can be
lost as the seal area rusts in tiny spots, and the food will be
exposed to air, moisture, whatever.

Ironically, very old cans of beer tend to go "flat", rather than
fermenting, so you just can't win.

Even MREs (modern "C-Rations") have an official shelf life of
only 5 years, so any bought in fear of Y2K chaos should be eaten
or tossed out soon.  I've been told that pouches of freeze-dried
"camping" food will store for much longer, but I've never eaten
freeze-dried anything, as my wife is a strict traditionalist when
it comes to cooking, and considers "canned goods" to be nothing
but last-ditch emergency blizzard supplies.
