plywoodwalls
I live in a rental and want to avoid permanently renovating the walls. And I have very little home improvement experience.
I would like to temporarily attach plywood to the interior walls in a way that doesn't damage the paint underneath. The plywood wont be structural.
How would you affix the plywood to the wall and be able to remove it later?
And how do you panel the wall evenly so it doesn't look like a jigsaw pattern?
Your solution is fine. I have seen that done a lot. Although, steel studs are used more often in this type of setting. I think I would use a Hilti gun instead of concrete anchors, this will save time, money and be more secure just because you can have more nails than you could ever put anchors.
TJIs of some sort making it virtually certain that the wall is not load bearing. The same joists are holding up the same second story over the same span beyond this wall.
If the wall was a properly built load-bearing single-top-plate wall every stud would be exactly under a joist. Its not load-bearing.

The short answer is that you can't. Plywood is heavy and you will need to drive a lot of screws through the wood and drywall into studs to properly secure it. You will also find that when you have something sandwiched tightly against paint, often it will pull the paint off when you remove it.
That being said, screw holes in drywall and peeled paint are easy to patch and paint when you are done.
As for avoiding a jigsaw pattern, you will just need to align all of the pieces correctly so that the seams are all in-line with eachother. The chance of the standard-sized sheets of plywood fitting exactly are very unlikely so you will need either a table or circular saw to cut them to size.
I'm not sure what your exact requirements are, but you might also want to consider particle board.
