I know others in universities have used their laptops to connect to their universities networks and then used the MAC Address from the laptop connection on the Xbox 360. This should be possible with the Xbox One as well by adjusting the alternative MAC Address
and replacing it with another already connected device like a laptop.

Is it possible to connect my xbox to my laptop and use my laptop as a tv?

NO, your laptop have an HDMI out, you can workaround this using Xbox Companion App on Windows 10.

If both Xbox One and your laptop use ethernet connection to your network, you can play without any issue.

It's a combo modem/router provided by our ISP Rogers - there are no antenna's

Wired connections to router = one laptop & one printer

Wireless connections to router = one laptop & our xbox 360

Hope this answers your questions.

No, do not connect your Xbox One HDMI out into your Laptop HDMI out port.

If your laptop and Xbox are on the same network, then you can stream the Xbox to your PC with the Xbox App.
