Correction:
Transactional Log Backups can only be initiated after a Full Backup is taken. However, after that, it captures all changes from the previous Transaction Logs and not dependent on Full Backups or Differential Backups. The only way you can break it is when you change the Recovery model from Full to Simple or when the existing Backup set is overridden when creating a new backup set media.
