Hi JackH,
Welcome to the community,
With the information I have available to me this does not seem possible to remove, the device will let out a vibrate to let you know there has been a message/email alarm etc, this is because your handset is set to notify you when something of this nature occurs.
Sorry,looked around and not sure but maybe if you have hangouts or other 3rd party app for messages,you might be able to disable the vibrations. However,not sure if during a call this will help.
You can relate to XDA if you find something.
