Should our son be transferred from Al-Azhar, or should he remain there, given that his memorization of the Qur'an is weak and there is concern that he may not complete his Azhari studies?

If his transfer to regular schools free of Sharia-prohibited matters is feasible, then there is no harm in that if his academic level does not qualify him to continue Azharite studies. However, if these schools are not free of Sharia-prohibited matters, then what we deem appropriate is to keep him in Al-Azhar and strive with him to raise his academic level, coupled with frequent prayers for him and creating a suitable atmosphere for studying.
