I've seen the phrase "color latitude" pop up several times in various articles but I'm not sure what it means exactly. Could someone point me in the direction of an article or explanation please?

Various film stocks and sensors are capable of capturing a limited set of colors within the entire range of visible wavelengths. "Color latitude" could theoretically be narrowed by, for example, under-exposing by 2 stops or telling the lab to do bleach bypassing while processing your film.

So when a film stock or sensor is able to reproduce a greater number of colors across the spectrum it is said to have more color latitude?

It probably means that the person who wrote it doesn't know the term "gamut".

I haven't heard the term "color latitude" though one could say that recording more color information gives you more flexibility -- latitude -- in color-correction and in pulling chroma keys.
