Can I use a wooden flat screw head with a washer to mimick a pan head screw?

For example - I am installing a fold up table from Ikea, it needs to hang from the wall, https://i.imgur.com/ZDVHaJs.png, it explicitly says to use pan head instead of flat screw heads like shown in the picture, I would drill into hollow concrete and will use nylon anchors but my question is, would a washer on a flat screw head be a hack here to do the job of the pan head screw?

It's not just about the shape of the head, but the flank angle of these two screws are different, also those have two different threads, anyway as far as the construction is static, and you use steel ring (washer) not rubber, then yes the ring provides enough surface for torque.

It seems reasonable to believe that the flat head (countersunk) screw would apply enough force to split the wood, hence the restriction.
If you use a flat head screw and the washer prevents the countersunk portion from exerting wedge-type force on the wood, you will have accomplished the objective.
Consider also that if you use a fender washer (large diameter), the compression force is going to be distributed over a wider area, providing more confidence in not damaging the wood brace.

Hey, that is not wood, its actually metal, pretty hard one. Also, I was wondering why they do not even use washers in their example, even though its pan head, wouldn't that be better?

I think using washers in the kit would be better, but for a manufacturer, it's an additional expense for product and handling. Even though the brace is metal, a countersunk head can distort the hole, resulting in a loose fastener over time. You'd have to check the tightness of each fastener at least once a year if you used countersunk screws.

^this is the correct answer. A thick washer that will not distort under continuous tension like the thin metal of the bracket would) with a countersunk screw will work fine. A Pan head isn’t so hard to come by, however, so I’d just follow the guidelines, personally.
