Here
I have 100 Vuser license with my LR Controller. And I run 100 Vuser
with no think time. In real scenario, the average user think time, fill
out information, is around 20s. Obviously, the application server load
is much higher at the same number of Vuser if Vuser has no think time
at all. So, if the application can just handle 100 Vuser load, then,
how many REAL users with normal 20s think time can this server handle?

Atleast 100 :-)
There is no such method or equations which gives you derived value you required.
In fact predicting or extrapolating performance results based on exiting test results is extremely risky.
