It depends somewhat on the details. But larger boards also tend to contain more pieces of new types. And, unlike variants that replace one of the pieces by another, they would certainly have no overlap in their game trees. Jean-Louis Cazaux's Metamachy (12x12), Gigachess II (14x14) and Terachess II (16x16) are clearly related, but each has its own article. OTOH, the article on Capablanca Chess discusses both the 10x10 and 10x8 version. But this could be because these both historically are called 'Capanlanca Chess'. The Ajax Chess article discusses both a 10x10 and 10x8 version with otherwise the same piece setup (but one with mirror symmetry, the other inversion symmetry). I have separate articles for the related variants Makromachy (14x14) and Megalomachy (16x16).
If a rule is to be derived from these facts, it would be that if variants that only differ in the number of empty ranks between the armies (with corresponding adaptation of the Pawn's initial push), and/or the orientation of the black army, should be presented in a single article.
