Is YQL and Document DB tightly coupled? Is it possible to separate YQL on another set of machines?

No, this is not possible.

This was answered on the slack forum with a workaround if you need it:

- blacklist some tservers so that they do not hold any tablets ( `yb-admin change_blacklist ADD` ) then they will act as query layer only
- disable YSQL (`--enable_ysql=true` ) one some others, that they will act as storage layer only
