Sure. But there is a lot of debate on if cropping hurts the image more than a crop sensor. I personally do not have much clarity on this.
If you want more clarity, check out my thread about just that topic:

In a nutshell, cropping an FF image to same FoV as a crop sensor, and just taking that image with a crop sensor in the first place is exactly the same thing, provided all other variables (sensor quality, physical distance to subject, lens in use, aperture, ISO, shutter speed, ...) are also exactly the same.
That's not what reach is about though. It is not about people not wanting to crop their images - it is about putting more pixels on the subject and therefore being able to display that subject larger. You can get that by physically enlarging the image more, using a longer lens. But past a certain point, that get's really expensive and heavy. The other way to gain more reach is using a higher pixel density, so pixels per sensor area. The highest Canon offers here currently is the 32.5 MP sensor found in the 90D and M6 II. Scaled up to FF area, that results in about 90 MP. And we have a good rumor indicating that will indeed be the resolution of the R5s (the high res RF body). But if that's the only option to get this kind of reach in the RF realm, it means you essentially have to pay a hefty premium over the other options to get that reach.
Previously there was the 7D II and 5Ds, which both had the same pixel density, with one offering all the advantages that come with FF, but at the cost of speed, and the other offering the same reach, but for a lower cost and with more speed. The camera in this rumor could well be hinting at a similar dynamic existing in the RF ecosystem in the future.
