I switch SD cards between a Canon T5i/700D and a Canon T2i/550D. One card has Magic Lantern set up for the T5i. Can the same card safely boot Magic Lantern in both cameras, or are Magic Lantern files specific to each camera model/firmware version?

Are the files on the SD card are the same for both camera models?
No.
Is it safe to boot Magic Lantern from any card in any camera (or at least on these two models)?
You should assume absolutely not. You can inspect the Magic Lantern source code yourself. But a strong hint is that the Magic Lantern binary download is specific to each camera model.
In the source code, there is a platform/<camera model> subdirectory for each camera model. The consts.h file in each of those subdirectories contains hardware-specific constants, firmware identifiers, memory addresses, flag values, etc.
Simply comparing the first 20 or so lines of platform\550D.109\consts.h and platform\700D.114\consts.h should be enough to convince you that the binaries are different, and that you shouldn't use the wrong Magic Lantern binary for each camera.

No—assume Magic Lantern is camera- and firmware-specific, so you should not expect one card setup to work safely in both a T5i/700D and a T2i/550D.
Magic Lantern builds are distributed per camera model, and the source code contains separate platform directories with different hardware constants, firmware IDs, memory addresses, and flags for each camera. That means the binaries and supporting files are not interchangeable across models.
In practical terms: a card prepared for a 700D should not be assumed safe for a 550D, and vice versa. If you want to use Magic Lantern on both cameras, prepare the card with the correct Magic Lantern build for each specific camera and firmware version.
