Not really, Peter Landin’s ISWIM is essentially syntactic sugar over lambda calculus, and went on to influence ML and Haskell. So there is a more direct lineage from lambda calculus to functional programming via that route.

(Regarding the sibling comment: Landin’s paper also predates Backus’ paper by about 10 years)

No idea how accurate it is, but Wikipedia says that ISWIM was influenced by Lisp...

That is correct.

From Landin’s paper:

6. Relationship to LISP

ISWIM can be looked on as an attempt to deliver LISP from its eponymous commitment to lists, its reputation for hand-to-mouth storage allocation, the hardware dependent flavor of its pedagogy, its heavy bracketing, and its compromises with tradition.
