Yea it would run on it linke any other distro, but you wouldn’t be able to multi task. I reasently installed Debian 32bit on an lenovo ideapead from 2013 with a 1 core 2 threads at 1.2ghz, 2G of ram and a HDD it runs KDE Plasma and will load anything as your pations are strong enough
But you could also run Alpine it will probably use less ram then debian. But I am farmiliar with apt, systemd and gnu software so yea. It is easier for me to give it to my small step sis as a research device with Firefox. I think Debian with KDE plasma uses about 630MB and with xfce around 300-400MB. But I think she is better of with KDE as she primary uses windows in school and it looks more like it
