Yes, it works and probably is safe, but there is the chance of some component requiring more power during startup and thus draining power so the pi does not get enough, turning if off in this process, which can corrupt your sd card.
I may be wrong, but if there is an intended pin for power supply, why not use it to be safe?

Because in the beginning those Zeros were really really rare, so to make sure everyone interested gets at least one, there were restrictions.
Now, there is no real need for this, since they are producing a lot of them every month.

I would prefer to power the screen directly from the powerboost and just wire the yellow cable to the pi
