If you are living abroad and receiving director’s fees from a Swedish company, you are liable for SINK taxation (special income tax for non-residents) on your fee, regardless of where your work was performed.
Keep in mind that you need an official decision about SINK from the Swedish Tax Agency, for the payer to make the right tax deductions.
Tax treaties with other countries could entail tax exemption in Sweden in some cases. You can read more about the tax treaties and double taxation here.
