Transport category aircraft is shared between 2 air carrier's. There is a discrepancy between the minimum equipment lists of the 2 airlines. Thus, an unserviceable item that can be legitimately deferred by one carrier, may not be deferred for the other carrier, causing the aircraft to be considered unairworthy.

Narrative:
We operated flight dfw/hou. Air carrier Z interchange with air carrier B aircraft arrived from sea with various deferred items--all air carrier B deferrals. One of the items was nbr 2 engine. Reverser imperative (placarded 3 days earlier). I assume air carrier B in sea (where placard was issued) had followed air carrier B maintenance procedures as outlined in the MEL--since they issued a placard for this item. Only air carrier a procedures had been followed. Inadvertently this flight was operated.
