Yes, sure. Both my Nvidia and Intel cards on which I tested this have ARB_buffer_storage extension, but none of them allow drawing from buffers mapped without appropriate flag.
FWIW that doesn't generate an error on macOS (which doesn't support ARB_buffer_storage); the GL spec is quite clear that it should be an error.
