Maybe, from a user-level perspective it does not matter, because you can run the Raspberry 3 in ARMv7 compatibility mode, and the GPIO pins might be the same and so on. From a system developer perspective it actually differs a lot. Raspberry Pi 1 has an ARMv6 based SoC, Raspberry Pi 2 ARMv7, and Raspberry Pi 3 ARMv8. Broadcom might re-use the same ip cores with its different SoCs, but there will be differences in MMIO addresses, interrupt numbers, RAM addresses and sizes, system-level registers, and so on. You might try to use a Linux kernel from the time it was initially ported to run on Raspberry Pi 1, and try to execute the same binary on the Rpi 3.
