The following terms struck me as uncommon, and on checking, I have not found them used:

• air squares
• capture leap
• CVPhile
• distant square
• finite mover
• heraldic piece
• infinite mover
• leap passively
• leap square
• line move

These have been used very little:

• capture zone is used in Outer Space Chess, where it is defined as " the set of squares on which a piece could potentially capture another, were it to be there."
• counter. While the word appears on numerous pages, I did not find any using it to mean a physical object used as a Chess piece, and it was sometimes used to mean another object used in conjunction with a Chess piece to alter its attributes or identity.
• custodial capture is used in Minima and Latrunculi XXI.
• cycle. While used in English Progressive Chess, as mentioned in the entry, I did not find any other game using it in the same sense.
• leap to capture is used once in Leap Chess, though apparently with a less strict meaning.
• line piece is used in Omega Chess and Grander Chess.
• marker is more commonly used to mean some object on the board besides a Chess piece. Same problem as counter.

These are terms I personally consider unconventional and do not use:

• array (I favor setup or initial setup)
• cell (I favor space)

I'm going to take a break now and continue this later.
