I don't think so.
First, we remember that the team was supposed to meet at the station, and the ones holding hands seems to be with them too. And we also must consider that Kayano was already there when the team arrived at the campus.
So, we have Maehara, Isogai, Fuwa, Kataoka, Okajima, Yada, Kimura, Chiba, Hayami, Hara and Mimura.
Then, we could add that, as you can see, both wrists aren't covered by any sleeve; yes, they could have rolled up their sleeves, but it wouldn't make much sense. So, it excludes Kataoka, Chiba, maybe Fuwa (though we can't see where her sleeves reach) and makes even more sure that the feminine hand isn't Kayano's.
Moreover, I'm not sure about Isogai, because, as we can see, his hands are both occupied; but he could have laid the bag or the broom in the station. Yes, it wouldn't make so much sense, but I'm considering every possibility.
In the end, the only possible popular ships it could be are Isogai/Kataoka and Kimura/Yada; although, Isogai has the problem we first said, and Yada canonically likes girls (it's stated that she had a crush on Kataoka), so I personally think it's a ship that we never saw, like, I don't know, Fuwa and Mimura, or Hara and Okajima, or anyone you want.
