Check "11.4.4 Destructuring with ‘pcase’ Patterns" section of Elisp
manual. It has examples explaining how backquote pattern works.

To not complicate things, I suggest something simple along the lines of
(lambda (&rest suffix-spec)
(pcase suffix-spec
(`(,key ,desc ,fn ,transform) ...)
(`(,key ,desc ,suffix) ...)))
Remember that you can always play around with things in scratch buffer,
in IELM, or even just using C-x C-e from anywhere:
(pcase '(1 2 3 4)
(`(,key ,desc ,fn ,transform)
(format "key: %s; desc: %s; fn:%s; transform: %s"
key desc fn transform))
(`(,key ,desc ,suffix)
(format "key: %s; desc: %s; suffix:%s"
key desc suffix)))
;; => "key: 1; desc: 2; fn:3; transform: 4"
(pcase '(1 2 3)
(`(,key ,desc ,fn ,transform)
(format "key: %s; desc: %s; fn:%s; transform: %s"
key desc fn transform))
(`(,key ,desc ,suffix)
(format "key: %s; desc: %s; suffix:%s"
key desc suffix)))
;; => "key: 1; desc: 2; suffix:3"
