Yes, a tuber is a special sort of stem. But because plants enjoy
confounding our best efforts to "pigeonhole" them, there are cases where
stem tissue may be transitional to root tissue. One South African Dioscorea
sp. was found to possess both root and stem tissue (at the anatomical
level) mixed within its rootstock.

Potatoes are interesting in that they propagate by stolons and form a
larger network for a single plant (please correct me if I'm wrong on this).
What could be called a more 'orthodox' tuber is solitary, static and
accumulates mass over time-- Cyclamen, many Sinningia, Begonia x hybrida,
