Canon 400mm f5.6

Would canon 7D Mark ii's auto focus work with Canon 400mm f5.6 when 1.4x extender attached? I know the autofocus will work with 1d series when 1.4x extender attached, I was wondering if it works with the newer SLRs.

I think it is just from habit.   Did a parade today and, yes, the Mk IV and D3 was along.  But its only 90 here with 90% humidity.
