Penn State U. says pig weed seed can remain viable up to 40 years.

That sounds just awful. Can you burn it out?

They _can_ but would be highly unlikely in lawn to be dormant anything
at all like that long.

_Most_ seeds if dry and not heated too hot will survive quite long
periods of time so that's not terribly uncommon.

But in a lawn there's almost certainly going to be enough water that
they'll germinate with a few years at the outside.
