My home setup is a Zyxel VMG1312-T20b as a bridge modem, and a Mikrotik hAP Lite TC as my router.

The hAP Lite is micro usb powered: https://mikrotik.com/product/RB941-2nD-TC
Code: [Select]
Powering
Details
MicroUSB input Voltage 5-5 V
Number of DC inputs 1 (MicroUSB)
Max power consumption 3.5 W
Cooling type Passive

The VMG1312-T20b power consumption is a follows: https://www.zyxel.com/uk/en/products_services/Wireless-N-VDSL2-Gateway-with-USB-VMG1312-T20B/specifications

Could I power the Mikrotik from the Zyxel, should I, should I not?

Surely it depends upon:
  • The supply capability of the PSU powering the ZyXEL device.
  • The maximum current that can be drawn from ZxYEL device's USB port.

I think you might be pushing it somewhat as I would only expect the Zyxel USB to be a standard 500mA one (ie 2.5 Watts).
