Han-Wen has answered your question.

However, for that particular example, you can define a function that
builds a \mark.

\layout {
  \context { \Score \remove "Mark_engraver" }
  \context { \Staff \consists "Mark_engraver" }
}

tempoMark = #(def-music-function (parser location markp) (markup?)
              #{ \once \override Staff . RehearsalMark #'self-alignment-X = #-1
                 \once \override Staff . RehearsalMark #'no-spacing-rods = ##t
                 %% eventually, some other overrides here
                 \mark \markup { \bold \italic $markp } #})

{ 
  \tempoMark \markup Allegro
  c'
}

You can not get rid of the explicit "\markup", though.
