A list of strings is a markup list. However, not every markup list is a
list of strings, so you might be on the safer side by using markup list
processing commands rather than string processing commands.

That's more a case of
Known issues and warnings
.........................
The markup-list argument of commands such as ‘#:line’, ‘#:center’, and
‘#:column’ cannot be a variable or the result of a function call.
(markup #:line (function-that-returns-markups))
is invalid. One should use the ‘make-line-markup’,
‘make-center-markup’, or ‘make-column-markup’ functions instead,
(markup (make-line-markup (function-that-returns-markups)))
So:
\version "2.19"
#(define-markup-command (function-A-taking-markup-list layout props
input-list) (markup-list?)
(interpret-markup layout props (make-concat-markup input-list)))
#(define-markup-command (feed-split-string-into-A layout props str)
(string?)
(let* ((strings (string-split str #\,)))
(interpret-markup layout props
(make-function-A-taking-markup-list-markup strings)
)))
\markup {
\function-A-taking-markup-list { a b c }
\feed-split-string-into-A "d,e,f"
}
