Is it possible for a PowerShell script to read the .tclogx file (TestComplete's output file)

Hi nish_b - 

I dont believe that powershell would be able to read the  .tclogx file because this is specific to TestComplete. That being said - I would suggest exporting your results to a more generic format, the available option for TestComplete would be JUnit. 

Here is some information on how to save the test results to a specific format from a script: https://support.smartbear.com/testcomplete/docs/reference/project-objects/test-log/log/saveresultsas.html

Let me know if you have further questions. 

Cheers,
