Yes, no problem. There isn't anything in there that would react to
form a gas and increase pressure significantly inside the jar.
The only time I can think of that finishes could "blow up" under normal
conditions (without extreme heat, sparks, etc.) is via spontaneous
combustion. This occurs when the finish polymerizes or catalyzes, and
the polymerization builds up heat, and when there's enough heat, some
fuel, and some air, spontaneous combustion can occur. The main way
I've heard of this happening is when a finish-soaked rag is wadded up
and left for a while, especially in a warm area - the rag provides lots
of surface area and possibly some insulation, so the finish can
polymerize quickly and build up heat. As long as the rag is spread
out, the heat can dissipate and it shouldn't be a problem, or I know
that some people submerge used rags in cans of water.
There isn't enough surface area for this to happen in the jar/can - if
anything, you might get a skim of polymerized finish on the surface of
your jar, but I've never heard of spontaneous combustion happening in a
partially-full container.
Good luck,
Andy

I cut some BLO with thinner a while back and stored it in an old yeast
bottle - the kind that's tinted dark brown. Not because of the tinting,
but because of the size of the bottle. I can't remember when I did that;
it was in the summer sometime. It's been fine ever since.

Sounds fine to me.

It will be fine until it comes time to remove the cap. Put a piece of
waxed paper or plastic wrap around the jar threads before screwing on
the lid. IME BLO always causes a vacuum inside a container when
stored, not pressure. It will use up and absorb any oxygen in the
container trying to cure.

I keep my BLO + turpentine mixture in an old hand soap dispenser, with the
push down squirt top. If there is any pressure in the bottle, it dribbles
product out the dispenser.
It doesn't.
You're safe.
