trades can only include players from the 60-man player pool. it's unclear if teams are permitted to include cash or a player to be named later in a deal. a player to be named later was permitted in this deal. furthermore, the named player had a spot on the 60-man club player pool, but had been removed from his club's cpp, but had remained in the organization. so, presumably, provided you've had cpp status at some point in 2020, you can be traded. also presumably, when reporting to your new club, you must be assigned to that club's cpp--either to the alternate training site or the major league roster.
