It is possible that Big Mom is the Emperor at the most disadvantage against Luffy. While no pushover, there were hints that her powers require an element of fear to work, and we all know Luffy is too brave (or dumb) to fear anything. And building off of my Buggy comment, I thought he got the Warlord position cause the World Government assumed that he was as strong as Shanks and merely played the part of an Almighty Janitor due to their shared history?
