You are required to file the total salary income from April 2015 to March 2016, i.e, as per both forms 16 of Companies A & B, (provided you had not declared your previous job to company B.)
No, there won't be any penalty, if you file your return even now. In case of any additional tax liability, interest over the same would be added, thats all.
