I don't think it was simply the word 'knickers' that made people uncomfortable with what Len said - although I admire the way posters have used that diversionary tactic 
I think it was the fact that he suggested Christine should whip her knickers off and wave them in the air (or words to that effect).
Admittedly, that WOULD be a 'performance'. However, it's not really the kind of 'performance' that Strictly is looking for.
I know it can be difficult to explain 'performance', but Len has - by his own claim - years of experience in judging. Is that really the best he can come up with?
All that said, I think Len would just about have managed to get away with that line (on the basis of Carry On type humour). He overstepped the mark when he started ranting at Craig for challenging him.
That rant, IMO, had a number of subtexts. One of those subtexts, I think, was Len's realisation that his comment - given recent BBC scandals - could get him into trouble. So he displaced all the blame onto Craig
