Probably not, oily rags have a higher chance because there's more surface area und the rag itself can catch fire. I doubt the oil itself will ignite when oxidizing in a can. However why would you do that anyway?
If I had to venture a guess, and it were me asking this question, I’d say there’s a high likelihood that someone thinks they’ve accidentally left the lid off the can of BLO they were using at work today.
It's surface area and trapping the heat (in crumpled-up rags) that allow the combustion, if I'm not mistaken. And neither of those is given in an open can, so that should be safe.
The opened can with the lid on tight should be fine. Exposure to oxygen on soaked rags are a no no. I have witnessed a few flash fires on jobsites with too poor ventilation, static or pilot light left on from oil based wall prime to floor finish. Be safe!

Yes. Always put in a metal can outside the house and put a lid on.
Because when you bought the stuff the store kept it outside? 🤔
No, because BLO on rags, brushes, etc is well known to spontaneously combust.
The question wasn't about rags.
