Well, if you want to call it in this way, it's fine. "Cackling goose" is an alternative common name (well, all common names are alternative) for the group of smaller subspecies of Canada goose, grouped together under the """""species"""""" Branta "huchtinsii" by some modern authors. The subspecies minima (as you can see in the title) form part of this "species" too (so it can be represented under the name Branta huchstinsii minima instead Branta canadensis minima)
