Yes, because the silent king is now CORE, says the new balance dataslate. And rites of reanimation say you can reanimate a dead model from a CORE unit. All necron vehicles are now CORE. I dont expect this change to last, because its utterly stupid. I expect titanic units and the silent king to be excluded from this change.
Rites of Reanimation: In your Command phase, you can select one friendly <DYNASTY> CORE unit within 6" of this model. One destroyed model from that unit is Reanimated. If the selected unit is a NECRON WARRIORS unit, D3 destroyed models from that unit are Reanimated instead. Each unit can only be selected for this ability once per phase.
GW once again changes rules without thinking about the consequences. They see necrons need help, and after drinking the 10th beer in the pub the rules team decided to give all necron VEHICLE core. Thats how they write their rules.
