Yes. The threads on threaded steerers except French are almost all 24 threads per inch (some Raleigh steerers use 26 tpi).
Busdriver is right; just move the fork cone (also called the crown race) from the old Le Tour fork to the replacement fork. Doing this ensures the fork cone will be compatible with your Le Tour headset.
