In theory.
And it actually probably would be pretty easy to do following US requirements, seeing how lax some of the “Made in USA” labels are:

Made in USA of Imported Parts
…the final construction is done in our country, but all or nearly all the parts have been imported from other countries
Made in USA with Global Components or Global Materials
…the final product is finished in the United States. There could also be a few or no parts of the product that are made in the US, but the majority are made and imported from foreign countries.
Assembled in the USA
…the majority or all of the product is put together in the United States or its territories. …it’s a foreign product, with foreign-made materials that were only Assembled in the United States. -https://www.allamericanmade.com/what-does-made-in-usa-mean/

But the logistics of funnelling $450 billion worth of parts through somewhere else would be basically impossible.
…or they could just lie.
