Edit: sorry, my bad, none of nRF51 SoftDevices support ATT_MTU change procedure, all are capable of default size (23B) only. Note that using BT SIG specification version for feature list is pretty confusing, none of them demands ATT_MTU exchange procedure as mandatory features so you can have BLE stacks (like several Nordic Soft Device types/versions) which are certified as v4.1 or v4.2 but don't support that. It's similar with other features (like PDU extension), always reed detailed spec/feature list not just BT SIG version mentioned in certification documents.
