Yes, a TV can go on nearly any wall, but the anchor and the method change completely depending on what the wall is made of. Getting that wrong is how a TV ends up on the floor.
Drywall over wood studs
The most common wall. The mount bolts into the wood studs behind the drywall. Drywall alone never holds a TV, so the whole job is about finding and hitting the framing.
Plaster and lath
Common in older valley homes. There are still wood studs behind it, but the plaster is brittle, so it takes care to drill without cracking the face and to reach the framing behind the lath.
Brick, stone and tile
Solid masonry. It holds a TV very well with the right masonry bit and anchors, drilled cleanly so the face does not crack. This is the norm on fireplaces.
Concrete and block
Common in apartments and commercial buildings. Masonry anchors rated for the load hold a screen solidly, without touching the neighbor.
Metal stud
Common in offices and newer commercial walls. It needs the right toggle or a ledger spanning studs, because metal stud is thinner than wood and a normal wood screw will not hold.
