Changed company from X to Y during H1B process


Currently I am working in TCS and applied H1B visa through some X employer, luckily my visa got picked.

Now, my Petition falls under Request for evidence, so i am giving answer to them. They have given end date for answering is Jan 28th meanwhile I got good offer in HPE (Location in india only) and expected joining date is Jan 11th.

Can i change the company from TCS to HPE on Jan 11th or not? What should tell about current organisation while H1B visa stamping if i change the company?.
