The Stem usually has the first notehead as its parent, and \hideNotes is
defined as

%% hideNotes

hideNotes = {
  % hide notes, accidentals, etc.
  \override Dots.transparent = ##t
  \override NoteHead.transparent = ##t
  \override NoteHead.no-ledgers = ##t
  % assume that any Beam inherits transparency from its parent Stem
  \override Stem.transparent = ##t
  \override Accidental.transparent = ##t
  \override Rest.transparent = ##t
  \override TabNoteHead.transparent = ##t
}

So you could use

{ <f' \single \hideNotes b'> }

instead (to break the relation between Stem and b') or just use

{ <\hide b' f'> }
