My Ops Specs (and AFM) limit me to 10 kts tailwind component for both t/o and landing.
Is it "possible" to operate at higher values? Sure, given enough runway I can both takeoff and land. It just ain't legal.
I don't know "why" 10 kts was chosen. I guess it's just a reasonable round number. It's been around a long time. (Way before high bypass turbofans.)
