I assume that all the slots on your pool are already busy, else this queued job would soon start running....

So I thus assume what you want to do is run this job instead of some other job that is currently running.

Administrators have the power to do this! :)  Specifically, users specified in the condor_config with QUEUE_SUPER_USERS 
have the power... by default user root and user condor are QUEUE_SUPER_USERS.

The solution is to use the condor_now tool.  On your submit host (where the schedd runs), su to root (or to any other 
QUEUE_SUPER_USER), and then run condor_now with the job_id of the important job you want to run now, and the job_id you 
want to vacate and give the resources to your important job.   Do "man condor_now" for details, or see
  https://htcondor.readthedocs.io/en/latest/man-pages/condor_now.html

Hope this helps,
Todd
