I think you'll have to make the note heads invisible:
\override NoteHead #'transparent = ##t

then the ledger lines should still appear (untested!)

YES!  Indeed, ledgers still show with your recommendation

Hi Javier,

I'd prefer to change \hideNotes, \unHideNotes from property-init.ly to affect dots, beams and accidentals too.

\version "2.14.2"

% see property-init.ly

customHideNotes = {
  % hide notes, accidentals, etc.
  \override Dots #'transparent = ##t
  \override NoteHead #'transparent = ##t
  %\override NoteHead #'no-ledgers = ##t
  \override Stem #'transparent = ##t
  \override Beam #'transparent = ##t
  \override Accidental #'transparent = ##t
}
customUnHideNotes = {
  \revert Accidental #'transparent
  \revert Beam #'transparent
  \revert Stem #'transparent
  \revert NoteHead #'transparent
  %\revert NoteHead #'no-ledgers
  \revert Dots #'transparent
}

\version "2.14.2"
 \score
    { \new Staff \with {
        \remove Bar_engraver
        firstClef = ##f
        }
         {
              \customHideNotes
          a''4  c''' c' a \break
               \customUnHideNotes
          a''4  c''' c' a
         }
        \layout {
         indent = 0\in
         ragged-right = ##t
         }
     }

Cheers,
