No, there are a set amount of enemies in the Boyle Mansion. I've possessed the Music Box Overseer by the dessert, taken him upstairs and knifed him. Got distracted and when I came back down, the second was on his way over. He had vacated the area by the front entrance by the http://dishonored.wikia.com/wiki/Boyle_Party_Guest_Ledger and took up position by the stairway leading up.

This happened on more than one occasion, so I can verify this.
