Because the tunnel is pretty much just concrete and nothing else. There's no flammable asphalt or high-voltage electrical cables running through it that could cause or contribute to fires.
Why wouldn't it need a fire suppression system? Because once a battery pack has started catastrophic failure, they are all dead anyways? The proposed system has more need for fire suppression than conventional subway, not less.
