Yes. It is possible to claim capital allowances in any later year’s tax return, as long as the assets are still owned in that later tax year.

I don’t have sufficient taxable profits to benefit from capital allowances. Should I bother with them? 

Yes. In our experience it is always best to identify capital allowance qualifying expenditure promptly. Firstly, you may have other income, or profits elsewhere in a group of companies, that the capital allowances can be offset against. Secondly, when you become profitable and have used all your carried forward tax losses, then the capital allowances will be invaluable. Many allowances can also be ‘disclaimed’, which means identifying and agreeing the amount qualifying for tax relief up-front, but choosing to defer claiming the relief until it is actually needed. On a number of occasions we have seen businesses short-sightedly failing to claim capital allowances because they are loss-making, and then not claiming in later profitable years when they need the relief.
