I would not rely on on a lag screw, especially where it could spin/rotate.
I put a pair of 2x4's with 1/2" plywood spacers across 2 joists (attic) and
used a threaded eye bolt/locknut and a 3/4" plywood "washer" to hang a sim
ilar chair, and likewise on a "floating" corner of a loft bed, rather than
a corner post to the floor...

Porch swings are hung using eye bolts. It depends on how large (diameter) the eye bolt is and how long it is, to have more than enough threads into the joist. I wouldn't trust or feel comfortable with a 1/4" eye bolt, which looks, to me, what that is.
I vote: No.
two 1/4" eye bolts (forged, fully closed eye, not home depot) should support a load
of 1000 pounds.
for non-forged (wire, i.e. not fully closed) eye bolts, the limit is 50# per each 1/4"
As Leon says, the screw should have full thread depth in the wood; we
don't know what size the screw is nor pilot hole was drilled so can't
comment on what might be the actual installed strength of the connection.
"Safe" depends on what the maximum working load is going to be as well
from a purely practical standpoint without consideration of any

Person I used to know made slings for people who engage in
"alternative lifestyles". His general rule was that if it wouldn't
hold a Hemi, it wasn't strong enough (yes, he had a large Chrysler
engine that he used as a test article).
