No. Getting people who live in "safe seats" to go and help local party organisations in "target seats" is called "mutual aid" and is practised by every political party, groups like Labour's "Momentum" movement and also by other non-party campaigners, too, such as Trade Unions. It is a standard practice in the democratic process. If you see the Prime Minister or the Leader of the Opposition visiting a constituency not his or her own during an election, that is also "mutual aid".
