Not with Nordic stack as far as I understand, all S110/120/130 versions support only default ATT_MTU size (for memory reasons - it requires certain amount of RAM).

Devices will settle on lower from two maximums so if one device supports max 23 the ATT_MTU stays on 23. Also how you can set MTU size through Android API and what stack supports such high value (1500)? Sounds pretty unreal.
