No you can not. The microchip doesn't track the owner or pet per say. The purpose of microchip is that if your pet was to go missing and someone found him/her they would be axle to be returned to you much quicker. It's like a permanent name tag.

The microchip does not have GPS tracking capability. It is only design to be able to be scanned if a pet is found, so they can contact the owners. If it is not scanned directly from the pet it is not used, thus it will not affect you/anyone GPS wise.
