Apple has historically be very stingy about RAM in iPhones. It looks like modern RaspberryPis today have 2, 4, or 8gb. The current-gen iPhone SE has 3gb, 11 standard/pro/max have 4gb. They're in the same ballpark. So it is possible, but Apple is so incredibly focused on mobile I can see them still investing in a custom filesystem focused on SSD, low memory overhead, per-file encryption, firmlinks, and whatever custom stuff they add for system updates, securing the boot volume, etc.
