I'd say yes. You are allowed in practice to play different nt ranges in different seats and vulnerabilities and allowed the conventional followups even if the union of all your nt ranges in all your seats is greater than the 5 point limit (so long as any given 1nt opening is within the limit).
Likewise, nearly everyone plays a 4th seat 2 level bid with a different range than 1st-3rd.
