Any EV can be charged to 100% any time.
However, spending a lot of time at high state of charge can increase degradation of battery capacity, depending on the battery chemistry. “High” depends on the battery chemistry, and may be >55% (most Teslas in the US), >60% (most non Tesla EVs in the US), or >70% (some Model 3 and Mustang Mach-E standard range in the US).
