No, you can only get a foreign tax credit for taxes paid on income that is taxable on your Federal return.
Income earned (such as dividends) within your IRA account is not taxable on your personal return until you take a distribution from the IRA.
Even then, the distribution from the IRA does not retain the character of the earnings that were in the account. This means that if you took a distribution, then you cannot say that the distribution was due to the foreign stock dividends, and therefore you must claim the foreign tax credit.
