Short answer. Yes, to the Bureau, within ten days of receiving notice. Article 236 allows a decision of the Labor Relations Division in the regional office denying registration to be appealed by the applicant union to the Bureau within ten days from receipt of the notice.

The route and the period, in one sentence
Article 236 provides that The decision of the Labor Relations Division in the regional office denying registration may be appealed by the applicant union to the Bureau within ten (10) days from receipt of notice thereof. Three things are fixed by it. The appeal goes upward from the regional office to the Bureau. It is taken by the applicant union itself. And the period is ten days, counted from receipt of the notice — not from the date written on the decision, and not from the day the officers happened to meet and discuss it.
Ten days is short, so start with the date
The first thing to establish, before anything is drafted, is exactly when and by whom the notice was received. Write that date on the file. Keep the envelope, the transmittal, or the logbook entry at the union office. In organisations run by working members in the evenings, a denial can sit unopened for several days while everyone assumes someone else has dealt with it, and the period does not wait. Decide immediately who is responsible for the appeal and give that person the papers.
Answer the ground actually given
A denial states reasons, and those reasons are what the appeal has to meet. Read them closely and address each in turn rather than arguing the merits of the union in general. Where the ground is a defect in the documents — an unsworn certification, a missing attestation, a list that does not tally — say what the true position is and put the corrected material before the Bureau. Where the ground is a conclusion you dispute, identify what in the record supports your position.
Keep the organisation intact while it is pending
A denied application is a difficult moment for a young union, and it is the point at which members most often drift away. Minute the decision to appeal, keep a complete copy of everything filed at the regional office and everything filed on appeal with the dates of receipt, and keep members informed in writing so the account circulating in the workplace is yours. If the officers who certified the documents have changed in the meantime, note that too, since the Bureau will be looking at papers signed by people who held office at the time of filing.
