If what you're asking is whether you can do something like


    . <first command> &
    . <second command>


at the Stata prompt -- where the second command would begin executing  
before the first has finished -- the answer is no.  If you find  
yourself spending a lot of time waiting for commands to finish (e.g.,  
because you are working with very large datasets and/or are doing very  
computationally-intensive analyses), then you probably need to  
structure your work differently (or, depending on the situation,  
perhaps consider a hardware upgrade and/or Stata/MP).  For example,  
you can break different tasks into separate do-files, and then run  
these as separate processes in your OS.
