Possibly, but I wouldn't guarantee it. Take the plug out and crank the engine. Note if anything comes out the plug hole. If oil comes out, check the oil level, and check that it IS oil in the sump (as opposed to rain water, or fuel and oil due to a leaky carb).
Check the no-load battery voltage. Less than 12.6 means a dead cell. Even a booster won't compensate for this.
