You cannot do this setting from within a markup command,
as far as I know, but you can easily define a macro
centermarkup = {
\once \override TextScript #'self-alignment-X = #CENTER
\once \override TextScript #'X-offset =#(ly:make-simple-closure
                    `(,+
                      ,(ly:make-simple-closure (list 
ly:self-alignment-interface::centered-on-x-parent))
                      ,(ly:make-simple-closure (list 
ly:self-alignment-interface::x-aligned-on-self))))
}

that you can use like

c^"Left aligned" \centermarkup c^"Centered" c^"Left aligned again"

Of course you can change the macro name to something shorter
if you want to save typing.

The alignment is done by aligning a reference point tied to the
note with a reference point tied to the markup. As long as you
have left aligned markups, I hope you agree that it makes sense
to have them left aligned with the note head, i.e. the reference
point of the note head is at the left edge, so that's why the
reference point of the note is not at the center by default.

I agree that it would be a nice feature, though.
