floor structure upper floor/ load-bearing wall?

[Nicklick]

Hello!
Recently moved in and unfamiliar with houses, so we thought we might ask a question in this knowledgeable forum!

The house is a so-called modohus, built in 72. Prefabricated house delivered with an unfinished upper floor if I understand it correctly.
The thing is, we are thinking of tearing down the wall between the kitchen/dining room on the ground floor but are not quite clear on how the floor joists run on the upper floor (to avoid accidentally tearing down a load-bearing wall).
The obvious assumption is that the wall running through the house would be the load-bearing one, but when we look at how the beams run in the ceiling, I'm doubtful...



Lifting up a board in the side attic, you can see that the joists (possibly too slight to be the floor joists?) run contrary to what we thought, meaning along the long side/ridge and not across.

You can also see the same regarding how the roof decking is nailed on the ceiling of the dining room on the ground floor. C/c 40, also c/c 40 between the studs in the wall we plan to tear down.
There is also a larger (beam?) that runs in the "correct" direction, see picture.

So the question is: Can we tear down this wall or should we consider another solution with a beam?

Very grateful for any answers!

One must be a little cautious when dealing with prefabricated houses. Without access to the original assembly drawings, it is difficult to understand how the house is constructed. I don't think the wall you want to tear down has a load-bearing function, but I can't say for certain.
