Compute Module 4S

Can the Raspberry Pi Compute Module 4S be used with the Organelle M and S? It looks like it was designed as an upgrade to the Compute Module 3 and 3+ for people who don’t want to redesign to use the Compute Module 4. Can it be used with the M & S? I realize the neither of those units is available at present but I could try finding a used one.

Unknown. From :

Compute Module 4S is intended for specific industrial customers migrating from Compute Module 3 or Compute Module 3+ and is not for general sale.

I was kind of hoping C&G was one of those specific customers since they have a current product using the older version.
