Agreed, although I would call it flat out verbal weight. The
BRB tells us the boxes on a detachment's chart have to be filled by the appropriate battlefield role. The section in the codex describing unit entries tells us the icon determines battlefield role. The icon is pretty much the only thing that lets you use a particular unit to fulfill an
HQ choice in a detachment. There is nothing implied or nonverbal about it.
From a practical standpoint, I think it would make more sense to have the Retainers rule be a part of the Archon unit entry. It triggers off selecting an Archon and not off selecting a Court of the Archon.
BEGIN NON RULES RELATED RAMBLING
The ideal situation, if the intent is to only allow Courts WITH an Archon, would be to create a Retainers or Bodyguards Battlefield Role. Give the Court of the Archon this role in their unit entry. This would prevent you from taking the Court alone as there isn't a Retainers or Bodyguards box on the force org chart of any current detachment or formation.
Then, give the Archon a special rule like this:
Entourage of Pain: For each Archon in a detachment, add an empty Bodyguards box to the detachment's force org chart.
You would, in effect, only be able to take a Court when an Archon is present. Just some rambling on how I would fix this if the intent is to limit the selections. Current
RaW doesn't limit the selection.
