I have a modern Philips TV with Android (it's connected to my local network). I can simply cast the screen of my Android phone but Is it possible to use TV as the second monitor for my laptop with Ubuntu 20.04 via wi-fi?

Your TV must have an HDMI port. You can certainly connect your laptop to the TV with a HDMI cable.
Sort of, with the proper Gnome Shell extension:
