Yes, but less so. Much of the chemical energy and ignition potential is removed by discharging the battery, but many of the remaining components (electrolyte as an example) are still flammable.
If punctured or heated sufficiently it definitely can self-ignite, especially if the battery had some wear and tear. The resulting fire (or explosion) will be a lot less spectacular than if the battery were fully charged, but all lithium batteries can be dangerous if treated badly.
