What’s the difference between macro mode and using a telephoto zoom for close-up photos?

I’m confused about how a camera’s macro mode differs from simply zooming in with a telephoto lens. For example, if I want to photograph a small flower, what changes when I switch on macro mode instead of just using a longer focal length and filling the frame by zooming? Is macro mode mainly about magnification, focusing distance, or camera settings?

Macro mode on compacts usually zooms to the longest setting, and DSLR lenses with a macro setting will only allow to engage it when fully zoomed. Edit: this may not be true for all models as mentioned in the comments.
When you turn on macro mode, the lens is able to focus closer than normally possible, and the AF system may be tweaked to prefer close objects.
So, if you are able to make the shot you want without engaging macro mode, that's perfectly fine, but you may need it so you can get closer to your subject and still get it in focus.
A macro or flower scene mode, as opposed to a macro switch on a DSLR lens, may of course tweak other settings, too, like aperture and colours.

The main difference is usually focusing distance and magnification, not just zoom.
A telephoto lens makes the subject appear larger because of its longer focal length, but it still has a minimum focusing distance. If you get too close, it won’t focus. Macro mode is designed to let the camera or lens focus much closer than normal, which allows higher magnification of small subjects.
With true macro lenses, this is described by reproduction ratio (for example 1:1), meaning the subject can be projected onto the sensor at life size. Most ordinary telephoto lenses do not reach that level of magnification.
On compact cameras, “macro mode” may also change autofocus behavior to prefer nearby subjects, and some cameras may adjust other settings such as aperture, color, or scene processing. On some lenses, a macro setting may only work at certain zoom positions.
So if your telephoto lens can already focus close enough to frame the flower the way you want, macro mode may not be necessary. But macro mode is what helps when you need to get closer and still achieve focus and greater magnification.
