No, if the company asks you to work remotely for their convenience.

If you believe you qualify to have your wages not be treated as Pennsylvania income, then you don't need to provide anything to Pennsylvania unless your W-2 shows Pennsylvania wages and state tax withholding, in which case you should file a Pennsylvania nonresident tax return.
