As you ask ....
FCL.700 Circumstances in which class or type ratings are required
(a) Except in the case of the LAPL, SPL and BPL, holders of a pilot licence shall not act in any capacity as pilots of an aircraft unless they have a valid and appropriate class or type rating, except when undergoing skill tests, or proficiency checks for renewal of class or type ratings, or receiving flight instruction.
FCL.740(b) is about Class or Type Ratings, nothing to do with LAPL.
