Chuckle suggests a barely audible series of sounds expressing private amusement or satisfaction: a delighted chuckle.
A smile is a (usually pleasant) lighting up of the face and an upward curving of the corners of the lips (which may or may not be open); it may express amusement or mere recognition, friendliness, etc.: a courteous smile.
