Yes, sure, but you could inject this during parsing. If you need this within a 
markup command there would not really be a reason why you shouldn’t be able to 
do so:

loc =
#(define-scheme-function (mup) (markup?)
   (markup #:override (cons 'location input-file-name) mup))

#(define-markup-command (test layout props) ()
   #:properties
   ((location "na"))
   (display location)
   (interpret-markup layout props location))

\loc\markup\test

The parser could very well (whenever creating a markup) set a location 
property.
