Can i Use a standard F-test on longitudinal data for a linear multiple regression?

What are you trying to do, exactly? Generally you wouldn't use linear regression for longitudinal data without some modifications.
 
I am studying companies over 7 years with 4 independent variables. I am using both random effects model and fixed effects model. The regression results include an F-test for the coefficients of the independent variables. But when I am to describe how the F-test is calculated, is it different from a situation where all data is collected from a single "moment"?
