You could keep a variable with the amount of validated items:

validatedItems : 0,

mobile : {
    var self = this;
    required: function(element) {  
        if ($("#telephone").val().length > 0) {
            self.validatedItems--;
            return false;
        }
        else {
        self.validatedItems++;
            return true;
        }
    }
},                                               
telephone: {
    var self = this;
    required: function(element) {
        if ($("#mobile").val().length > 0) {
            self.validatedItems--;
             return false;
         }
         else {
            self.validatedItems++;
            return true;
        }
    }
},

And then you could check if one or more items are validated when you send the form:

if( validatedItems > 0 ) {
    sendForm();
}
