There is no harm in trying. It is purely cultural (spurred by diaper companies) that we don't usually train children until much later. Kids younger than 2 are usually happier to train because they still want to please you. If you wait until after 2, they get defiant, and you almost have to wait until 3 or 4.
My son was day trained by 21 months. Basically, you have to start by putting them on the potty 6-8 times a day. Don't give up diapers at this point; just keep putting him on the potty. Keep him busy on there as long as you can. Read books, sing songs, let him brush his teeth, anything to keep him on there.
When he does finally go for the first time, praise him a lot. Teach him the sign for potty. Then keep going. Soon he will go whenever he sits on there (usually pee first). At this point, you should put him cloth diapers without a cover or training pants with no cover. Pay attention to when he drinks and how much and when he pees afterward. Usually you have to put him on the potty every 25 minutes or so at first. Set a timer, sing a potty song, act excited, whatever you have to do to get him on there. As you catch each pee, he will begin to go longer in between pees, except when he is having fun at the park or playing, etc. At this point, do not go back to diapers at all during the day. If you do, he will regress. Also, be very careful not to ever get angry or frustrated if he wets his pants. You have to be calm all the time or he will begin to hate the potty. If at any point he starts to fight it, step back a little. You can't make him hate it or he won't train until he's 3 or 4.
The entire process will take 2-3 months. Don't expect him to tell you he has to go until he is around 2. But if you take him, he will go. Don't go on long drives. Take a potty to the park.
If this sounds worth it to you, go for it. You will be glad you did, and he will be glad not to sit in wet diapers all the time.
Good luck!
