I think short answer it is if you think it is!
but if you approach it from a more dogmatic angle then it's probably not bulletjournal. i think the major concepts are around how you log your day, and what rituals you have to reflect on what you log. theres a more strict system in place and even being analogue is part of the system. I dabbled with a digital bujo before but i dropped it, and i switched to analogue, following the system more closely and ive been doing it for 4 months now!
