As long as the CG is ahead of the neutral point then you still have positive stability. The neutral point is not the centre of lift of the main plane but of the entire aircraft.

Of course the amount of stability required is set by the certification standard so military aircraft can be designed with neutral or negative stability and use FBW systems to make them flyable by a mere mortal pilot. He does get the option of a martin baker arrival though in case the systems fail.
