Yes @Starryfifty it can be removed.
The precedent was set by George V who had to remove the British Prince title from his cousin Charles who was the posthumous son of Prince Leopold , Duke of Albany. Poor Charles was forced by his family to go and live in Germany to run the Dukedom of Saxe-Coburg-Gotha.
He had a childhood plagued by illness and was very close to his sister Alice (Of Athlone, longest living grandchild o& Queen Victoria). He was sent to Germany at only 15 years old as it was believed he could be ‘re educated ‘ as a German as at that point he was terribly English.
He was a man of two countries -his German subjects & Aristocratic peers didn’t like how English he was, so he sided with Germany during WWI and lost his German titles dur8ng the German ‘revolution’ and he lost his British titles (held since birth) as a result of siding against his cousin and the British Empire.
So not just AMW. We have full, proper precedent set.
And if Harry carrys on pretending he’s a workimg royal, harassing the Home Secretary for security , sueing his fathers government , accusing judges of ‘whitewash’ during a high court case because he’s lost, then arguing with letters sent, that the Palace -not the King, the Palace - have been Forced to Send because of his actions , to every person who would need to be informed of Royal visits/protocol to inform them he is not a working royal no matter what he says then the King absolutely has to remove every title.
Harry is painting himself very very quickly into a corner. He is leaving the palace with no option. They will HAVE to shut him down for national security.
He cannot be swanning off to places like The Ukraine and being treated as if he is representing the King, The Government and the Country.
Private Individuals are not allowed to behave like this.
It’s really really becoming untenable.
Or MI6 kidnap him and take him to some deep underground bunker at Porton Down and we never see him again.
Either way. I really don’t mind.
