local lore that the name is derived from the box bush "buxus sempervirens" is improbable. there is no supporting evidence at all, and "buxus" is not native to the area. there is, however, a connection with beech. box (wilts), box (glos), box hill (surrey) and places such as boscombe (wilts) and le bosc (france) all feature extensive beech woods growing on various limestones.
