You can have as many accounts as you like, on one platform or on all of them. What you can't do is play more than one at once. Even then if you have 2 computers you could log into 2 accounts at the same time. But if you press W on a keyboard only 1 character should move forward - if they both move then that's botting and can get you banned.
The thing that's confusing me about your post, and the thing that might be a problem for you is that you said you've only purchased the game once.
If you mean you only have 1 disc and/or 1 copy of ESO installed on your PC then that's fine, but you'll still need to buy a second copy of the game because you can't use a second account without a product key associated with it and the only way to get one of those is to buy the game.
So you could have bought a boxed copy of ESO originally, used that disc to install the game and then later bought a digital copy and used that to create a second account, skipping the step where you download the game. But you can't simply create a second account for free and log into the game with it.
