Yes, you can, but provide everything as indicated:
Team Name:
Entered Cars (between 1 and 4)
Starting numbers for the cars(00; 02 - 99):
License Applications for the team (real name / LFS-ID / Gender / Nation [in ISO 3166-1 alpha-3])
d
.
BUT... you need either buy yourself in to Tiger Express Motorsport, to keep your number, OR you need to choose a new one.
Just tell me if you want to take it, and I'll take another number for us.
