Could UTF-8 theoretically be expanded in a non-breaking way to include a vast new language and still support all existing software?

Presuming a large language that was discovered, and we wanted to support the language in our existing computer systems, is UTF-8 designed in a way to allow for their possibly vast amount of characters?

For instance, if the language consisted of millions of newfound glyphs, symbols, and/or combining characters, could UTF-8 theoretically be expanded in a non-breaking way to include these new glyphs and still support all existing software?

I'm more interested in if the glyphs far outgrew the current size limitations and required more bytes to represent a single glyph. In the event UTF-8 could not be expanded, does that prove that the single advantage over UTF-32 is simply size of lower characters?
