Yes, but JPEG acceives that by use of a compression algorithm which is
inappropriate for use with a transparency mask, so if such information was
needed it would either have to be compressed in a different manner (such as
PNG offers), or the transparency information would have to be out-of-band
(such as the SVG solution described by others).
