Thank you very much for taking the time to reach the Intel® Communities Team.
I understand you would like to know if changing the TDP setting on your computer will generate any problem to your system. I will be more than glad to assist you further.
Allow me to share with you that change this feature should not have any repercussion on your system. The only change you might be able to see is the performance of your machine if you set a lower frequency on your processor nonetheless, I would highly recommend you verify with your system manufacturer to confirm if your system is capable to support this changes.
I hope this answers all your questions.
