No, not legally. (And also not in reality)
1955 were the treaties, conventions, protocols and schedules of the Bonn-Paris Conventions, the Pariser Verträge in German. The treaty terminating the occupation of (West) Germany was the revised “Convention on Relations between the Three Powers and the Federal Republic of Germany”, in German often short „Deutschlandvertrag“. The three powers in article 2 of that convention explicitly reserved the rights for Berlin and Germany as a whole and relevant for this the right to station armed forces in Germany (article 2, articles 4 and 5).
The 1955 conventions were a package deal. Part of it was the “Convention on the Presence of Foreign Forces in the Federal Republic of Germany”, which further assured the Three Allied Powers right to station forces in Germany, although limited to what was already there.
Both conventions were only to be terminated by all signatory states or by a future German reunification agreement and peace treaty. That was in effect the “Treaty on the Final Settlement with respect to Germany“ of 1990, the 2+4-treaty, in which the allied powers, including the Soviet Union, terminated their rights. Hence final settlement.
