I looked at this cpu support list for the motherboard http://www.cpu-upgrade.com/mb-ASUS/TUWE-M.html and it seems you can use 1.4Ghz celeron but not 1.4Ghz P3.
Anyone has any idea why 1.4Ghz P3 would not work?

Well, that's a 3rd party site where users test and report CPUs as working or not, not an official compatibility list. Maybe simply noone's tested and reported PIII 1.4 GHz as working with that board 😀

FWIW, these old lists from ASUS suggest slightly different support

Thanks. I always thought they combined both user tested and officially supported in that site because in the past they pretty much matched what manufacturer had said on their site.
