I haven't tested it but the gamedata file has a signature for l4d2, so it should, if that signature is still valid.

"left4dead2"
{
"Signatures"
{
"CTerrorPlayer_OnVomitedUpon"
{
"library" "server"
"linux" "@_ZN13CTerrorPlayer13OnVomitedUponEPS_b"
"windows" "\x55\x8B\xEC\x83\xEC\x2A\x53\x56\x57\x8B\xF1 \xE8\x2A\x2A\x2A\x2A\x84\xC0\x74\x2A\x8B\x06\ x8B"
}
}
}
