Is it permissible to accept the will of a Muslim woman residing abroad who allocates her financial assets to build an orphanage or support charitable organizations?

There is no harm in accepting the will and being appointed as an agent to dispose of the woman's money for the purpose of building an orphanage or donating it to charitable organizations. However, there is a concern that this might be a trick or a scam designed to defraud you, obtain your account information, or profit from contacting you by phone, so caution is necessary.
