i believe yes because anko had the curse seal before orichimaru got his hand sealed by hiruzen.Since this part of orichimaru was seal ,this mean he will not be affected by hiruzen sealing jutsu from the death god.
I think he can move his arms but he cannot use ninjutsu because they were sealed by Hizuren. If you think abotu it when have you since having his arms sealed seen him perform a hand sign
