Yes:

%%%%
\version "2.20.0"

#(define-markup-command (arrow layout props size) (number?)
  (interpret-markup layout props
    (markup
      #:line
      (#:fontsize 3
      (#:general-align 0 -1
      (#:override (cons (quote thickness) 2)
      (#:combine
        (#:draw-line (cons 0 size))
        (#:arrow-head 1 -1 #f))))))))

arrow = -\markup \arrow \etc

\relative c' {
  c1^\markup \arrow #2
  c1^\arrow #2
}
%%%%
