Streaming · Plain-English answer
Partly. YouTube TV is only sold in the United States and checks your IP address, so a VPN connected to a US server lets the site load and play. However, Google also asks members to confirm their home area periodically and uses device location in its apps, so long trips can still trigger restrictions.
YouTube TV layers several checks. Your IP address decides whether the service loads at all outside the US and which local channels you receive. On top of that, Google requires you to use the service in your home area regularly and to confirm your location in the app every few months.
The mobile apps can also read device location directly. That means a VPN handles the IP layer cleanly, but it cannot answer a GPS prompt on your phone with a US location.
On a laptop browser, connecting to a US VPN server generally restores playback of your paid subscription, since only the IP address is visible. Choose a server near your home market if local channels matter to you.
Expect the home area check to catch up on extended stays abroad, because it is designed to. If Google asks you to verify from your home area and you cannot, parts of the service degrade until you do. A VPN changes where your connection appears to be, and this is one of the services that checks more than your connection.
