Are they both ly:book? behind the scenes?  If so, I can see the problem.

I suspect I am misunderstanding you.  Here is what else I have tried:

%%%%
\version "2.20"

bookFunc = #(define-scheme-function () ()
  #{ \book { \score { { b'4 } } } #})

% \bookFunc % fails - bad expression type
% \book { \bookFunc } % fails - bad expression type
$#{ \bookFunc #} % works?!
