Some terrestrial Utricularia seem OK with less light than the average CP.
Other than these, my CP have all wanted lotsa, lotsa, lotsa light.

So it makes sense to me that the classic carnivore habitat has poor soil (so it's a big advantage to catch bugs as a nitrogen supplement) and a ton of light (so it's not a big loss to grow less efficient leaves). It'd also explain why light-starved flytraps and sarrs grow trapless leaves and flatter pitchers, respectively. They're prioritizing light over trapping.
I'm sure there are exceptions though, like some of the bladderworts mentioned above.

Many non-carnivorous plants which grow in high light do not have wide leaves ... like grasses which expose even less surface area to direct sunlight than a sarr. Then there are cacti and some succulents which have gone the route of doing away with leaves entirely. So don't really think that carnivory has anything to do with narrow leaves.

Survive, maybe, but would it thrive? I had my calycifida on a west facing window, and while it was okay, I wouldn't say that it was thriving. Now it's outside in mostly full sun, and it's growing like crazy
EDIT: I just realized that "survive" is the point of this point, not necessarily thrive
