Can I travel While Company Name change in Process

Hi Experts

This forum is always a great help for me in all my application process.

My Sponsor has changed their Company name for the business need "Incorporating with sister company" this change has been notified to Home office in November 1st 2015, we haven't received any update on this yet. But in the mean while HR left the business without notifying or Hand over to new HR so new HR don't have login authority to SMS and cannot see any update for the name change. HR is in the process of obtaining the login details or changing to authorising officer. Now I have got travel plans to fly back to Home country is it save for me to travel while Name change is still in process or do I need to wait until the process is updated to Travel

Please need your expert advise

Thanks
