Arpeggios do work on single notes; they just don't show up because the
available space is too small.

When you have a chord with a squashed position, all the noteheads are
forced onto one staff line or space. The double slashes you're seeing
are two noteheads in the same chord squashed to the same staff
position. The arpeggio doesn't appear because it hasn't any room at
all.

The trick is to manually adjust the arpeggio's positions.

\new Voice \with {
  \consists "Pitch_squash_engraver"
} \relative c' {
  <f c'>4\arpeggio <e b'>4\arpeggio <d a'>4\arpeggio <c g'>4\arpeggio
  \improvisationOn
  c4\arpeggio c4\arpeggio c4\arpeggio c4\arpeggio
  \override Arpeggio #'positions = #'(-1 . 1)
  c4\arpeggio c4\arpeggio c4\arpeggio c4\arpeggio
}
