This is from the B&H site (describing the specifications for
PF Borax):
Synonyms
Biborate of soda
Biborate of sodium
Borate of soda
Borate of sodium
Purified borax
Pyroborate of soda
Sodium biborate
Sodium borate
Sodium pyroborate
Sodium tetraborate
Tetraborate of soda
20 Mule Team Borax
Borax is available as borax, pentahydrate, but most commonly
as borax,
decahydrate, the form used in photographic formulas. The old
term for
decahydrate is crystalline. Borax, decahydrate, and 20 Mule
Team Borax are
one and the same.
So maybe sodium metaborate is the only thing that *isn't*
borax.

See my last post. Metaborate is a boron compound but is
NOT Borax. It can be made from Borax and Sodium Hydroxide in
solution as detailed in that message.
