No. inject Subscriber object to your block object. or using object Manager for create Subscriber instance

Example: $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); $subscribe = $objectManager->create('Magento\Newsletter\Model\Subscriber'); $subscribe->subscribe(); //it works but not recommend
