Nearly. The G1 Dinobots didn't combine, by the way, though there are a few bits of fanart and an unofficial mini-comic which show a hypothetical Dinobot gestalt.
There are two main strands of TF combination technology: gestalts and power-ups. The original G1 concept was five or six individual Transformers which combined to make a single super-robot - the first version being the Constructicons, who were six similarly-sized robots, and afterwards superseded by the 'Special Teams' consisting of one larger 'team leader' who formed the torso and four smaller TFs who each formed a limb and were interchangeable.
Although the toys were labelled 'Combiners' at the time, the fandom roughly settled on the term 'gestalts' because the super-robot had a single mind formed from the merging of all the individuals who formed it. This is also why the super-robot had its own name and (usually) a bio of some kind. Hence six individual Constructicons (Scrapper, Mixmaster, Long Haul, Bonecrusher, Hook and Scavenger) formed the 'gestalt' robot Devastator; five Protectobots (team leader Hotspot plus Blades, Groove, First Aid and Streetwise) formed the 'gestalt' robot Defensor.
By contrast, almost every version of combining done since then has been of the 'power-up' variety. Mini-Cons in Armada were direct and obvious power-ups for the robot they were combined with; the Energon Powerlinx gimmick was less obvious since the two robots were usually the same size, but the combined form was referred to as 'Powerlinx [top robot's name]' AFAIK. It wasn't a separate character in its own right, as the G1 gestalts were, but a powered-up form of the same base character. Similarly, when Cybertron Optimus (Galaxy Convoy) and Wing Saber (Sonic Bomber) combine, the result is a powered-up Optimus in Sonic Wing mode (= Sonic Convoy) rather than a separate character.
There are one or two oddball exceptions to this - the G1 Duocons being the prime example - but generally combination in the TF multiverse fits into one or other of the two categories.
For reference, both are slated to eventually make an appearance in HMW. Powerlinx-style combination will probably come first, as it's a lot easier to implement, but G1-style gestalts are considered by many players to be the 'Holy Grail' of HMW.
--EDIT--
Yah, so AS got in there first, but I was more thorough.
