I'm not sure what you're referring to with "vocabulary stack" here, perhaps the dictionary? More of a linked list, really a distinctive data structure of its own.
Maybe OP refers to vocabulary search order manipulation [1]. It's sort of like namespaces, but "stacked". There's also the old MARKER and FORGET pair [2].
The dictionary pointer can also be manipulated in some dialects. That can be used directly as the stack variant of the arena allocator idea. It is particularly useful for text concatenation.
