Almost certainly not. https://en.wikichip.org/wiki/arm/26-bit_architectures https://en.wikichip.org/wiki/arm/26-bit_architectures https://en.wikipedia.org/wiki/26-bit_computing https://en.wikipedia.org/wiki/26-bit_computing Flags, processor mode, and the PC (24-bit) were kept in the same 32-bit word. That made it cheaper to store/restore on interrupt and, boy, did they want interrupt handling to be fast! Combined with the requirement for naturally aligned instructions, this gives the original ARM a 26-bit address space for code. They chose to make that the address space for everything -- so the address space was 64MB. The ARM926 came much later.
