Yes, using a wrong viscosity oil can be potentially harmful. Especially you should never change operational viscosity in a manner to choose lower viscosity oil except if manufacturer specifically said it's ok to do so. This is not the case here. There are no common rail diesels specifying 0w20 oils to my knowledge.
