No you need that sensor in for sure regardless of de cat or not.
If you run your car without it then the ECU will not get the air/fuel ration right and you'll end up with an ECU just pumping untold fuel in which will lead to car not starting and black spark plugs were too much fuel is being ignited.
As for a de cat... same problem. My friend got a full de cat and the lambda sensor wouldnt fit the new pipe so he did without.
Soon after the problems I've said occured and it wasnt til he fitted a lambda sensor that it got better. Altho damamge was done and the bills started to flow!
