Keep in mind that this is not my area of expertise, but my understanding is no. I don't quite get the "traversable" part, but the holographic part refers to the fact that they're not actually simulating a wormhole, instead they're simulating the equivalent of a wormhole under the holographic principle.

That is to say, you have two theories A and B and one of them is a quantum gravity theory with wormholes and another is a quantum field theory without gravity (nor wormholes) in it. The holographic principle tells you that these two theories are equivalent, which is to say that there's some kind of way to translate one into the other. They want to study wormholes in theory A, but it's too hard. So, what they do is instead they study whatever the equivalent of wormholes in theory A is in theory B. These are the "holographic wormholes". It's not that the wormhole itself is an hologram or something, rather it's that you study the equivalent object to a wormhole under the holographic principle.

Here's a discussion in r/physics on the topic, and a vulgarisation article by Strassler. Hope that helps.
