No. King Duncan was clueless. He admits it himself: "There's no art to find the mind's construction in the face; he was a gentleman in whom I built an absolute trust." He had no idea what was going on with Macbeth. Macbeth really expected to be named as Duncan's heir (he was after all a successful warrior unlike the feckless Malcolm) and was shocked and hurt when Duncan named Malcolm Prince of Cumberland. And then Duncan says "And now the party's at Macbeth's place!" He was, as I said, clueless.
It was Macduff who was knocking on the door after Macbeth killed King Duncan.
