Not all the details are out, but my guess would be no.

Trump's documents appear to be regarding national security, and he appears to have refused to return them, to the point of not returning these ones, which I would suspect implies criminal intent.

There may be other explanation for such a blowhard loudmouth. Perhaps he wanted to souvenir some top secret documents. He had a times cover of himself mocked up and framed, so self-aggrandisement is an important part of who he is. He's already referenced the documents Obama has in his presidential library, so perhaps he just stole these and refused to give them back because he's buggered if he's going to let Obama have records of his presidency and he not, and he's also buggered if he's going to go through the correct process, because that would take time and effort, and he's too busy running the business of pocketing money that the magahats donate thinking that it's going to challenging the election outcome in the courts.

Full disclosure: I suspect criminal intent.
