Interesting but that doesn't seem to likely,does it? The sentence says something along the line of "they resemble the male Dwarves so much that members of other races can't hold them apart." If the female Dwarves were wearing fake beards it would rather be like "they make themselves resemble the male Dwarves.." Since beards were a quintessential aspect of male Dwarves and females seem to be indistinguishable for the non-Dwarven eye,females in all probability had natural beards as well.
