Yes, you can use .45 cans on .45 cal weapons of different cartridge design, just as you can use .30 cal cans for 6.5mm blasters. The one thing with some of the pistol caliber cans is that you need to make sure you have a can rated for the rifle pressures if you are going to shoot higher pressure cartridges. A good example of this is .22 cans that will literally explode if subjected to .223/5.56 pressures. I've seen a lot of viable .22 cans made out of plastic, that would disappear from the muzzle blast of a .223 Rem.
The one-stamp barrel/suppressor combos are permanently attached, so a short barrel combined with a suppressor reaches or exceeds 16". Most suppressor makers will advise against it, but might offer it if they make sure their suppressor is perfectly concentric with your barrel. Baffle strike is a real issue that I have seen and dealt with on different occasions. Another con of a unitized barrel/suppressor is the difficulty to clean your can and pipe, but this issue can be handled with ultra-sonic tanks and other methods.
Back to the .45 suppressors. Most pistol cans require a Nielson device to allow the action of a semi-auto pistol to cycle reliably, since you now have totally changed the barrel weight and resistance to delayed blowback via the Browning method, which is the most common for locking semi-auto pistol breeches. The Nielson device basically allows the barrel to recoil normally, while the can stays in position temporarily, using a spring and somewhat floating mount. It is commonly used on pistol cans, and you will need one for almost all .45 ACP pistols. With the Nielson device (recoil booster), it might not be the best thing to mount on a rifle.
.45 caliber is also pretty disappointing to suppress, and most guys that get into cans and NFA items only mess with .45 once, usually against the advice of their friends. It's just too loud, no matter what you do. 9mm and .22 LR are a different story altogether. Conversely, .308 and 6.5's suppressed are much quieter than .223 suppressed in rifles, from all the cans I have heard. In the States, there is a lot more money required to buy cans than in Europe, so it is a pretty exclusive, but rapidly-growing market.
Unless you're shooting a high-end 9mm can or 300 Whisper, .22 LR Rugers integrally suppressed are one of the most fun guns to quiet down. A lot of other cans amount to more "cool factor" than anything else, although many precision rifle guys benefit from the accuracy enhancements from them.
