こういう事ですか？Button1を押してからButton2を押すとちゃんと切り詰められます
XE2です
void __fastcall TForm1::Button1Click(TObject *Sender)
{
int Cnt = PopupMenu1->Items->Count;
char *buff[] = {"Test1111111111111111111", "Test2", "Test3"};

PopupMenu1->Items->Clear();

for (int i = 0; i < Cnt; i++) {
TMenuItem* mi = new TMenuItem(this);
mi->Caption = buff[i];
mi->OnClick = MenuItemClick;
PopupMenu1->Items->Add(mi);
}
}

void __fastcall TForm1::Button2Click(TObject *Sender)
{
int Cnt = PopupMenu1->Items->Count;
char *buff[] = {"Test1", "Test2", "Test3"};

PopupMenu1->Items->Clear();

for (int i = 0; i < Cnt; i++) {
TMenuItem* mi = new TMenuItem(this);
mi->Caption = buff[i];
mi->OnClick = MenuItemClick;
PopupMenu1->Items->Add(mi);
}
}
