Question about Huawei CP84 SuperCharge

My guess is no. The charging standard is Huawei proprietary (SuperCharger), it does not use USB PowerDelivery.
Smartphones might just be able to be charged using the normal USB 2/3 standard (maybe max 2A at 5V), but that's not enough for laptops anywhere.
I would get a manufacturer-specific charger if I were you.

Unfortunately, I can't say for sure, because the USB ports on Huawei are USB C - type. I can't charge my Samsung devices with it, I think it should also not work for Dell devices. Also, I saw that your Dell laptop only has USB 3.1...? so the cable and plug should be compatible with that port. Also, it is questionable whether your Dell supports Super Charge.
