No, it can't.

If you don't have braceccl set, the cleanest solution would probably
use a function:

  compctl -K comp_tracks playcd
  comp_tracks() {
    setopt localoptions braceccl
    reply=( {1-$(cd-discid /dev/cdrom | cut -f2 -d' ')} )
  }

If you have braceccl set, something like this should do the job:

  compctl -s '{1-$(cd-discid /dev/cdrom | cut -f2 -d' ')}' playcd
