No it will not, better to use air tool oil or after run oil.
Most ARO is ATF anyway. When I actually use ARO, I use mineral ATF and Seafoam mixed at 4:1 respectively. Seafoam mixes with petroleum and alcohol. When the engine gets fired back up, it blows all of the ATF out. This mixture also does wonders for minimizing carbon.
ARO and ATF are completly different, ATF has detergent, wich will foul glow plugs, ARO and air tool oil are pretty close. WD40 will also foul glowplugs and cause headaches if used as ARO. For cleaning wd40 would be fine, but after i wouls spray it off with brake cleaner, and lube with machining oil or after run.
