Well yeah. The extreme being a tube exactly as big, or bigger than the tire, that wouldn't have to stretch at all. In which case stretch would be an unlikely reason for tube failures.
And this would have to be actual size, not size designation.
OP does say :"
Tire is a 25 mm Vittoria Corsa, which run on the bigger side for what they're marked. Tube is a Vredestein unpigmented latex tube, 23/25mm width"
If there is stretching - which seems reasonable according to above - a tube that's unevenly thick from fabrication will stretch at different rates depending on thickness.
Maybe enough to induce failure.
I've had that happen, so I'm suggesting a way to check for tube thickness consistency.
