Yes, I've bricked my old Macbook by doing that (for several months).
I bought a new laptop, so closed down my old Macbook, and stuck it away.
A few months later, I found I wanted to grab file from the old macbook, and noticed it wouldn't run from battery. It'll work fine plugged in, but the battery is registered as full discharged, and the Apple page says "Buy a new battery".
