In general yes, but again, unfortunately there are a lot of complicating factors. I can eat meals with 60g carb content and have my blood sugar levels barely move at all and I can also have, for instance, a beer with 15-20g of carbs that causes a 6 to 8 point rise. The trickiest part for me is finding the right balance between not having a massive meal peak, but also having stable levels in between meals. What works best for me personally is eating 'slow' meals i.e. meals that have a low glycemic index. These don't necessarily have to be low on carbs, but should be high in fiber, protein and unsaturated fats, which again is also very personal since each of our guts responds differently resulting in different rates of blood sugar production for different meals.
The problem with just eating low carb meals in my case is generally that it offsets the balance in between meals, i.e. I'll start seeing a consistent rise that might be something like 0.5-1 point per hour which eventually adds up. Of course you could increase your baseline insulin to offset that again, but it requires a lot of experimentation to get that balance right.
I do occasionally switch out my somewhat carb heavy lunch for a lighter low carb meal if I'm really busy and don't have time to go for a walk for instance. Generally that does work just fine to keep the initial rise low, but requires another 2 units of insulin about 2.5 hours after the meal because my blood sugar level keeps rising.
So in short, yes moderating your carb intake and especially ensuring your meals are slow are ways to make managing your blood sugar levels easier, but in my opinion it still requires experimentation to find out what works or does not work for you personally.
