My Dell Latitude 5420 stopped powering on, and the repair estimate is close to the cost of buying another used unit. If I purchase another Latitude 5420 and move the SSD from the broken laptop into it, should Windows boot normally since the operating system is already installed on the drive? The replacement may have an 11th-generation i5 instead of my old 11th-generation i7. Could that CPU difference cause compatibility problems?

The swap is very likely to work without reinstalling Windows. Even on somewhat different hardware, modern Windows versions usually boot, detect the new components, and download the necessary drivers. However, BitLocker is the main issue: disabling it before the swap is safest, but if it is already enabled, you will need the recovery key. You can often find that key through the Microsoft account associated with the laptop. If Windows will not activate afterward, you may need to reactivate it or perform a clean installation.
It should work, especially since both systems are the same Latitude 5420 model and use closely related 11th-generation hardware. Windows will detect the replacement system and install or update any needed drivers. The i5 versus i7 difference should not prevent it from booting; it mainly affects performance. Before swapping the drive, make sure you have a backup and locate your BitLocker recovery key. If BitLocker is enabled, the new motherboard may require that key. You may also need to check the BIOS storage setting—typically RAID or AHCI—and match the setting used by the old laptop. Windows activation might need to be completed again because it can be tied to the original motherboard.
If you are mainly concerned about recovering files rather than keeping the exact installation, you could put the old SSD in a compatible USB enclosure and copy the data to the new laptop. Another option is having a repair shop clone the old drive to the replacement laptop's SSD. Either way, preserve the original drive until you know your files and activation are safe.
If you can access the drive first, back up important files before installing it in the replacement laptop. A USB-to-NVMe enclosure or another computer can be used for that if the SSD is removable.
