This is like seeing Jesus in a cheese sandwich only in this case one actually has to fudge quite a bit - the cross-like model listed is only one of many possible representations and conformations and the one they glom onto because it looks like Jezus's cross is one of the most simplified versions (simplified = accuracy sacrificed for abstract utility).
Here's some actual laminin for an idea of the floppiness:

Of course someone will inevitably try to say it's close enough, which kinda misses the point, eh?
Ah, you beat me to the punch. I found it rather suspicious when I saw a cartoon of laminin, as cartoons tend to be idealised representations of a protein.
Even more suspicious was the fact that the particular post I went to, I found they had the picture the wrong way up to deliberately invoke an image of the cross:

Looks more like a sword to me, especially the bulky C terminal end. And if you look more closely, it's three strands and the two intertwined strands are more reminiscent of a caduceus. Not to mention that the shorter arms bind to other molecules of laminin to form laminin sheets, so in the body, you're not going to find a natural cross-shaped protein on its own.
Besides, the human mind is prone to seeing patterns and shapes where there are none, or drawing similarities where there are none.
